Calling 'handle_io_response()' in a regular VFS function (in contrast to a
post-signal hook) can cause problems if the caller of the VFS function holds
a lock which prevents the io response handler from returning.
With this commit, the user of the VFS becomes responsible for unblocking
threads which might be blocking after a failed 'queue_read()', 'queue_sync()'
or 'write()' call.
Fixes#2896
- initialize the stack size attribute with `Libc::Component::stack_size()`
as default value
- remove the possibly uninitialized `pthread` member from the attribute
structure and obtain current attribute values in the
`pthread_attr_get_np()` function, where the `pthread` object reference
is given as argument
- let each thread obtain its stack address and actual stack size at thread
start to have the information available for other threads
Fixes#2865
The libc will now use the file given by the 'nameserver_file' attribute
to get the DNS nameserver address instead of reading '/etc/resolv.conf'.
It defaults to '/socket/nameserver' which is the common location when
using the lxip VFS plugin. As a constraint the libc will read the first
line and expects the nameserver address without any keywords in front of
it.
Fixes#2861.
The component is no longer loads from '/test.pdf', the first PDF file
found in the root directory of the file-system is loaded automatically.
The behavior cannot be overridden by configuration.
Feed MuPDF with characters from input events to MuPDF rather than
translate raw key codes to ASCII. This enables almost all MuPDF key
bindings without the need to maintain a lookup table. Mouse navigation
has been enabled as well. To print the key-bindings to log, press '?'.
Fix#2859
- support saving of files with no file name extension
- make the the "All Files (*)" file selection filter the default to see
configuration files immediately
Fixes#2844
Properly initialize and reset the _owner member, otherwise
correlating the unlock operation with the respective read/write
lock does not work.
Move locking the _nbr_mutex in the unlock operation after the
owner check. Otherwise, a reader holding that mutex and waiting
for the write lock would deadlock a writer trying to unlock the
_global_mutex.

If ACPI IRQs are received but no changes to the watched state for a specified

Issue #2816
Rename LwIP library in preparation for removal of LwIP libc plugin. The
current LwIP library will be replaced with a new version stripped of its
synchronous socket support. The next version will be incompatible with
the current, so removing 'lwip.lib.so' completely for a period makes it
easy to identify legacy users.
Fix#2797
Generic code that operates over both UDP and TCP sockets might use
'sendto', but in the case of TCP the destination address ought to be
safely discarded. This seems to be the case for certain DNS software
that operates over both UDP and TCP.
Fix#2807
issue #2791
pthread_attr is not associated with any thread, the statistics must be
gathered at runtime, while 'pthread_attr_get_np' may retrieve attributes
by from any thread. Addtionally, the attributes given to
'pthread_create' will most likely be deleted after the creation call.
The sole existence of shared-object dependencies lead to fatal
static-constructor errors before. Now, ldso checks if the ctors section
of objects in the init list are non-empty before whining.
Issue #2759
Socket_fs sockets are now created each time a 'new_socket' control file
is opened, not each time a 'new_socket' file is read. When a handle on a
'new_socket' file is closed the socket and its socket files are
destroyed. The accept control file on a listening socket reads "1" or
reads nothing to indicate a client connection is queued. Client sockets
are accepted by opening an 'accept_socket' file in the listen socket
directory. This file behaves like the aforementioned 'new_socket' file.

This commit changes the 'Input::Event' type to be more safe and to
deliver symbolic character information along with press events.

The Ada runtime can now be set with the ADA_RTS variable. The ada
library builds a (currently) minimal runtime from the gcc sources that
come with Genode (to stay consistent with the used compiler) and sets
the runtime path accordingly. It is build as a shared library ada.lib.so
which needs to be added to the build files.
I split the existing Ada test into program and library, and moved it
to libports as it depends on the runtime library residing in this
repository too.
Fixes#2748
Reduce the size and forward compatibility of VFS file-system
constructors by passing an object holding accessors for 'Genode::Env',
'Genode::Allocator', response handlers, and the root file-system.
Fix#2742
In other words: Loosen the former property that suspend can only be
called from the first user stack and, thus, enable additional user
stacks, e.g., in coroutine libraries.
Fix#2737
This patch enables the use of the VFS from VFS plugins by passing a
reference of the root directory to the constructors of file-system
instances. Since it changes the signature of 'Vfs::Dir_file_system',
any code that uses the VFS directly requires an adaptation.
Fixes#2701
