cb952d2087 obscure File_system::Out_of_node_handles exception
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.

82a7799638 lib/vfs: pass handle allocator to open(...)
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.

338cfe5a94 sd_card: return capacity in 512kByte blocks
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.

44fe44e8b6 init: invalidate child-provided service on kill
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.

14f1ac497e linux: improve exception-signal handling
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.

051e84c4b4 Move server API concept to base framework
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.

febb0cc13d config: deal gracefully with invalid dataspace cap

cda07b7da0 base: simplification of the IPC code
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.

2490e399dc ldso: check binary pointer before lookup
Check if the binary pointer is valid before attempting to lookup the

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.
