3897ddea03 cxx: don't rely on global ctors
This patch removes the global variable 'blocker', which was expected to
be constructed via the global ctors. This mechanism, however, is not
used for the base library, which resulted in the use of an unconstructed
object. Specifically, the spinlock of the 'Lock' of the 'Registry'
defaulted to the LOCKED state (value 0), which eventually would lead to
a deadlock in the contention case of the cxa guard.

I could observe this deadlock once on during the component startup on
base-linux during the construction of the 'startup_lock'.

This patch fixes the problem by explicitly initializing the registry
of blockers via an init function.

697d496093 ldso: don't strip leading path from ROM name
This patch removes ldso's builtin policy of removing any path elements
prepending the ROM module name. Instead, the ROM name is used as is.
This clears the way to access different ROM modules that share the same
name but are stored at different directories behind an fs_rom (e.g.,
/bin/bash vs. /usr/local/bin/bash).

66d5359d75 ldso: heuristics for libs needed during execve
The allocation of regions within the linker area is normally left to the
best-fit 'Allocator_avl', which happens to populate the linker area
starting with the binary followed by all loaded libraried with no gaps
in between.

When replacing the binary during execve, however, we need to ensure that
the new binary does not conflict with any library that stays resident
during execve. This patch tweaks the linker's region allocation scheme
such that these libraries are placed at the end of the linker area.

fa48054959 ldso: Dynamic_linker::respawn mechanism
This patch extends the interface of the dynamic linker with the ability
to replace the running binary executable by another one. It is
designated for the implementation of execve. The interface consists of
two new functions.

'Dynamic_linker::keep' marks the specified shared object as unloadable.
This can be used to pin a set of libraries (i.e., the libc) within the
local address space while replacing the binary and other higher-level
libraries.

'Dynamic_linker::respawn' unloads the current binary, loads the one
specifed as first argument, and looks up the entry point symbol of the
new binary, which would be "main" for POSIX programs.

In addition to implementing the new interface, the patch adjusts the
linker at various places that previously assumed the binary to be
constant over runtime.

3c6fe6e741 ldso: statically allocate initial heap block
This patch enables the fork.run script to run on base-linux. It should
be regarded as an interim solution, however, because the randomization
performed by the Linux kernel may still - by chance - produce a
situation where one of the libc's malloc heap regions intersects with
another dataspace dynamically attached to the child.

The better solution would be to make the 'Region_map_mmap'
implementation not depend on the kernel's allocation policy by using a
locally implemented allocator.

fork operation.

This patch enhances the 'base/shared_object.h' interface of the dynamic

shared libraries.

The new interface is a base mechanism needed for implementing 'fork' in
the libc.

4000 ms.

the timeout framework, the timer session, the userland timer-drivers, and the
alarm framework on all platforms. The commit also adapts the code that uses
these tools accross all basic repositories (base, base-*, os. gems, libports,
ports, dde_*) to use unsigned 64-bit values for time as well as far as this
does not imply profound modifications.

35cf804471 base: free up all blocks on avl destruction
Issue #3111

remove_range may deny to the job on memory pressure or insane ranges,
which ends up in an endless loop when the Avl allocator is in destruction.

Since the Avl gets destructed, solely the memory free up is of importance,
not the correct range adjustments during remove_range.

67fd77d10a base: catch 'Ipc_error' in 'Expanding_parent_client::exit()'
If a component is being destroyed just before it calls `exit()` at its
parent, the `exit()` call causes an `Ipc_error` exception, which leads to
an `abort()` loop with repeated error messages, because `abort()` calls
`exit()` too. Catching the exception in `Expanding_parent_client::exit()`
avoids this problem.

57fd4e9148 Add Io_progress_handler to Entrypoint interface
The "schedule_post_signal_hook" method of the Genode::Entrypoint class
is problematic because the signal hook can be scheduled and replaced
multiple times during the signal dispatch cycle. Add an alternative to
this method with "register_io_progress_handler" and the "Post_signal_
hook" class with "Io_progress_handler". The difference being an
"Io_progress_handler" may be registered once during the lifetime of an
entrypoint to prevent arbitrary libraries from replacing a pending hook.

The "register_io_progress_handler" remains as a deprecated API, and is
now invoked for every I/O signal received and only for I/O signals
rather than for any signal.

5ed5fddb7c base/os: remove deprecated APIs
This commit removes APIs that were previously marked as deprecated. This
change has the following implications:

- The use of the global 'env()' accessor is not possible anymore.
- Boolean accessor methods are no longer prefixed with 'is_'. E.g.,
  instead of 'is_valid()', use 'valid()'.
- The last traces of 'Ram_session' are gone now. The 'Env::ram()'
  accessor returns the 'Ram_allocator' interface, which is a subset of
  the 'Pd_session' interface.
- All connection constructors need the 'Env' as argument.
- The 'Reporter' constructor needs an 'Env' argument now because the
  reporter creates a report connection.
- The old overload 'Child_policy::resolve_session_request' that returned
  a 'Service' does not exist anymore.
- The base/printf.h header has been removed, use base/log.h instead.
- The old notion of 'Signal_dispatcher' is gone. Use 'Signal_handler'.
- Transitional headers like os/server.h, cap_session/,
  volatile_object.h, os/attached*_dataspace.h, signal_rpc_dispatcher.h
  have been removed.
- The distinction between 'Thread_state' and 'Thread_state_base' does
  not exist anymore.
- The header cpu_thread/capability.h along with the type definition of
  'Cpu_thread_capability' has been removed. Use the type
  'Thread_capability' define in cpu_session/cpu_session.h instead.
- Several XML utilities (i.e., at os/include/decorator) could be removed
  because their functionality is nowadays covered by util/xml_node.h.
- The 'os/ram_session_guard.h' has been removed.
  Use 'Constrained_ram_allocator' provided by base/ram_allocator.h instead.

924e5c54eb core: fix RM-session upgrade mechanism
This is a follow-up commit of "base/core: use references instead of
pointers". Because the 'Rm_root::_upgrade_session' implementation
lacked the 'override' keyword, my overzealous change of the pointer
argument went unnoticed.

This commit fixes the depot_rom (cached_fs_rom) failure in Sculpt.
When cached_fs_rom attempted to create a new managed dataspace while the
RM session quota was depleted, it tried to upgrade the session (via
Rm_connection::create). However, the upgraded resources never reached
the actual session because the default 'Root_component::_upgrade_session'
was called instead of 'Rm_root::_upgrade_session'.

aa66b5d62f base: remove dependency from deprecated APIs
This patch adjusts the implementation of the base library and core such
that the code no longer relies on deprecated APIs except for very few
cases, mainly to keep those deprecated APIs in tact for now.

The most prominent changes are:

- Removing the use of base/printf.h

- Removing of the log backend for printf. The 'Console' with the
  format-string parser is still there along with 'snprintf.h' because
  the latter is still used at a few places, most prominently the
  'Connection' classes.

- Removing the notion of a RAM session, which does not exist in
  Genode anymore. Still the types were preserved (by typedefs to
  PD session) to keep up compatibility. But this transition should
  come to an end now.

- Slight rennovation of core's tracing service, e.g., the use of an
  Attached_dataspace as the Argument_buffer.

- Reducing the reliance on global accessors like deprecated_env() or
  core_env(). Still there is a longish way to go to eliminate all such
  calls. A useful pattern (or at least a stop-gap solution) is to
  pass the 'Env' to the individual compilation units via init functions.

- Avoiding the use of the old 'Child_policy::resolve_session_request'
  interface that returned a 'Service' instead of a 'Route'.
