943dfa10e7 base/child.h: remove exceptions from process init
This patch replaces the former Child::Process and
Child::Process::Loaded_executable classes by static functions that
return failure conditions as return values.

d44ec53cd3 core: tie Platform_thread to Platform_pd
This patch tightens the coupling of the 'Platform_thread' objects
with their corresponding 'Platform_pd' objects by specifying the
'Platform_pd' as constructor argument, keeping the relationship
as a reference (instead of a pointer), and constraining the
lifetime of 'Platform_pd' objects to the lifetime of the PD.

It thereby clears the way to simplify the thread creation since all
PD-related information (like quota budgets) are now known at the
construction time of the 'Platform_thread'.

The return value of 'Platform_thread::start' has been removed because it
is not evaluated by 'Cpu_thread_component'.

d866b6b053 Remove exceptions from Cpu_session interface
The 'Thread_creation_failed' error is now reflected as
'Thread::Start_result' return value. This change also removes the
use of 'Invalid_thread' within core as this exception is an alias
of Cpu_session::Thread_creation_failed.

0d7d60a1f4 Remove exceptions from Pd_session interface
This patch replaces exceptions of the PD session RPC interface with
result types.
The change of the quota-transfer RPC functions required the adaptation
of base/quota_transfer.h and base/child.h.
The 'alloc_signal_source' method has been renamed to 'signal_source'
to avoid an exceedingly long name of the corresponding result type.
The Pd_session::map function takes a 'Virt_range' instead of basic-type
arguments.
The 'Signal_source_capability' alias for 'Capability<Signal_source>' has
been removed.

1b313df419 linux: force stack area mapping at requested address
With `MAP_FIXED` absent from the mmap(3p) flags, "the implementation uses
addr in an implementation-defined manner to arrive at pa", which may
lead to a mapping at an address diffent to the requested `addr`.

Add `MAP_FIXED` to the mmmap flags to force mapping to the specified
address.

852bc3fc62 base-linux: remove exceptions from region_map_mmap
This patch replaces the exception-based error propagation by the use of
'Attempt' return values, which eliminates side effects of the exception
handling - cxx_heap allocations - from code paths that are used by the
the cxx_heap itself (when growing the cxx_heap).

It thereby fixes the failure of the sub_rm test at the "attach RAM ds to
any position at sub rm - this should fail" step.

This patch replaces the global '_wait_for_exit_sem' object by a local
static variable, which does not rely on the global ctors. It thereby
fixes the fault_detection test after the removal of the global ctors
execution from core ("base: remove component.cc from core").

1fd1786122 test/lx_hybrid: don't call glibc exit
This patch removes the use of the Entrypoint::schedule_suspend mechanism
and the call of glibc's exit from the lx_hybrid tests, for two reasons.

First, the interplay of atexit handlers executed by the glibc and
Genode's lx_hybrid library is complicated while bringing no benefits in
practice as lx_hybrid applications are usually servers that don't exit
anyway.

Second, the Entrypoint::schedule_suspend mechanism in not used by any
other component. By removing its use from the lx_hybrid tests, we can
remove this mechanism from the base library.

54cc70f9b1 base: remove Env arg from init_exception_handling

3489672bc0 base: remove env_deprecated from thread-start code
This patch replaces the internal use 'env_deprecated()' from the
implementation of the thread API in the base library. It also
replaces the global accessor 'main_thread_cap' by the explicit
propagation of the main-thread's capability to the single point of
use via a new 'init_thread_bootstap' function.

61926ebc07 base: introduce platform_init function
The new 'init_platform' function performs the platform-specific
component-local low-level initialization. It allows for the
differentiation between core and regular components as well as
kernel-dependent peculiarities.

This patch introduces a consistent notion of a 'Platform'. Within core,
the 'Platform' contains the kernel-specific initialization. Outside
core, the platform sets up the interplay with the parent component. In
all cases, the platform is constructed while running on the initial
stack.
