Replace the Out_of_node_handles exception with Out_of_metadata.
Clients need to know when the server is out of internal resources,
but not why.
Cleanup and sort the errors at file_system_session.h.
Remove 'Size_limit_reached exception' from File_system, which was
internal to ram_fs.
Issue #1751Fixes#1909
Opening a VFS handle previously involved allocating from the global heap
at each VFS file system. By amending open with an allocator argument,
dynamic allocation can be partitioned.
A new close method is used to deallocate open handles.

The returned capacity had different semantics dependent on the card
type. For HIGH_CAPACITY cards, the memory capacity is specified in 512kB
blocks. So we should also return 512kB blocks for STANDARD_CAPACITY
cards.
Issue #1925
When init destroys a child server with an open session, the client must
be updated as it will otherwise store a pointer to a no-more existing
service object which will be dereferenced when the child client is
destroyed.
Fixes#1912
First, we use an alternate stack for signal handling now. The stack is
shared among all threads of the component, which is okay as we only
handle exceptions with log output and pass on to the default handler
(that terminates the execution). The primary motivation for the
alternate stack is the detection of SIGSEGV due to stack overflows.
Also, hybrid components now handle exception signals by logging and the
support for multi-threaded applications was improved.
Fixes#1935
This commit introduces the new `Component` interface in the form of the
headers base/component.h and base/entrypoint.h. The os/server.h API
has become merely a compatibilty wrapper and will eventually be removed.
The same holds true for os/signal_rpc_dispatcher.h. The mechanism has
moved to base/signal.h and is now called 'Signal_handler'.
Since the patch shuffles headers around, please do a 'make clean' in the
build directory.
Issue #1832
Prevents the annoying warning about
WARNING: Image format was not specified for 'bin/test.img' and probing guessed raw.
Automatically detecting the format is dangerous for raw images, write operations on block 0 will be restricted.
Specify the 'raw' format explicitly to remove the restrictions.
If attached ROM dataspaces are not valid after update(), code that uses
these ROMs produces
void Genode::Volatile_object< <template-parameter-1-1> >::_check_constructed() const [with MT = Genode::Attached_dataspace]: Deref_unconstructed_object
In scenarios where the config ROM is loaded from a report ROM or any
other non-static ROM, config might try to access an invalid dataspace
capability. This patch prevents the component from aborting in this
case.
Fixes#1914
This commit replaces the stateful 'Ipc_client' type with the plain
function 'ipc_call' that takes all the needed state as arguments.
The stateful 'Ipc_server' class is retained but it moved from the public
API to the internal ipc_server.h header. The kernel-specific
implementations were cleaned up and simplified. E.g., the 'wait'
function does no longer exist. The badge and exception code are no
longer carried in the message buffers but are handled in kernel-specific
ways.

If ports need preparation in order to execute a run script, use the
knowledge about the actual genode directory to suggest a command to the
user that can be directly copied to the command line.
Rust relies on atomic builtins, which are not implemented in libgcc for
ARM. One is implemented in rust, which is sufficient to get the
current rust test to run.
Issue #1899
Check if the binary pointer is valid before attempting to lookup the
symbol. Shared objects with unresolved symbols and missing depencies,
e.g a library that references 'errno' but is not linked against libc,
will now produce an error message when they are loaded by the dynamic
linker.
Fixes#1904.
