With the '-x' argument of the 'g++' tool the language gets specified,
therefore it has to be 'c++' furthermore, not CUSTOM_HOST_CXX. Moreover,
when import-lx_hybrid.mk gets evaluated first, global.mk is not included
yet, therefore we cannot eagerly evaluate the CXX_LINK_OPT_NO_PIE variable.
Issue #3466
server.h:51:12: warning: ‘int write_avail_cb(socket_t, int, void*)’
declared ‘static’ but never defined [-Wunused-function]
This patch fixes the warning by moving the user of 'write_avail_cb' to
the compliation unit that defines it.
Even though the call of map.metadata is known to always return a valid
pointer (because the meta data is assigned in the code just above),
better add an explicit nullptr check.
`volatile` effectively prevents instruction reordering by the compiler
and fixes an issue with -O3 compiled components.
Note, this commit does not address further arguments regarding memory
barriers and volatile voiced in issue #693.
Issue #693
Incoming ACK packets for sent data packets may be the only unblocker for
suspended write/send loops. This patch informs VFS users about I/O of
VFS handle on successfully sent packets.
Store errno in pthread objects, return member upon call to '__error()'.
This became necessary in order to make errno thread-safe.
Note, any call to libc code from a non-pthread (beside the first
entrypoint) is not supported.

- Stop refreshing if all CPUs go to sleep, also in text mode.
- Any input resets update rate to 100Hz in graphic mode, which gets
decreased step by step down to 25Hz if no input is available (looking video
without input by user).
Fixes#3576
This commit uses CUSTOM_HOST_CC/CUSTOM_HOST_CXX instead of hardcoded
commands and introduces HOST_DEV_PREFIX.
Original patch by Roman Iten and Pirmin Duss.
Issue #3466
This is important to issue sync requests for written-to files.
As the closing must be performed by an atexit handler, it happens at a
time _after_ libc plugins are destructed. Consequently an FD allocated
by such a plugin results in a close error, which in turn, does not
destruct the FD. We ultimatedly end up in an infinte loop of
re-attempting the close. For this reason, the patch changes 'close' to
be robust against this special case.
This is generally not a problem because libc plugins are phased out.
However, at present, the libc_noux plugin is still important. With the
changed 'close' in place, there occurred an error message "Error: close:
close not implemented" at the exit of each noux program. This patch
removes the error printing from the libc plugin mechansim to avoid this
noise. The error messages are not important anyway because the
deprecation of the libc plugin interface.
Issue #3578
The getpeername function is provided only by the socket fs.
In the case where the socket fs is not configured, return an appropriate
errno instead probing for a libc plugin (there is none).
