uClibc variants do not provide the C99 long double math functions like ceill,
powl, etc.. For future compatibility use check_symbol_exists() to check
whether these functions are available, and keep the result in
HAVE_MATH_C99_LONG_DOUBLE. Use that instead of the fragile Cygwin version
check in triodef.h.
Fixes build failures under uClibc(-ng) like:
../../libwinpr/utils/libwinpr-utils.so.0.1.0: undefined reference to `powl'
../../libwinpr/utils/libwinpr-utils.so.0.1.0: undefined reference to `fmodl'
../../libwinpr/utils/libwinpr-utils.so.0.1.0: undefined reference to `ceill'
../../libwinpr/utils/libwinpr-utils.so.0.1.0: undefined reference to `log10l'
../../libwinpr/utils/libwinpr-utils.so.0.1.0: undefined reference to `floorl'

It's unclear why this option would be necessary, and it causes problems
when people do not match it to their toolchain and CFLAGS.
To set the float abi, either use a toolchain with an appropriate default
or set the float-abi option in the CFLAGS environment variable.
This should resolve#2586.
uClibc master branch, as well as uclibc-ng add eventfd_{read,write}
definitions. Instead of testing for __UCLIBC__, have cmake explicitly check
for the existence of eventfd_read and save the result in
WITH_EVENTFD_READ_WRITE.
Fixes build errors like:
.../winpr/libwinpr/synch/event.c:120:12: error: static declaration of 'eventfd_read' follows non-static declaration
static int eventfd_read(int fd, eventfd_t* value)

1)
Added missing checks for CreateEvent which also required the
following related changes:
- changed freerdp_context_new API to BOOL
- changed freerdp_peer_context_new API to BOOL
- changed pRdpClientNew callback to BOOL
- changed pContextNew callback to BOOL
- changed psPeerAccepted callback to BOOL
- changed psPeerContextNew callback to BOOL
2)
Fixed lots of missing alloc and error checks in the
changed code's neighbourhood.
3)
Check freerdp_client_codecs_prepare result to avoid segfaults
caused by using non-initialized codecs.
4)
Fixed deadlocks in x11 caused by missing xf_unlock_x11() calls
in some error handlers
5)
Some fixes in thread pool:
- DEFAULT_POOL assignment did not match TP_POOL definition
- don't free the pool pointer if it points to the static DEFAULT_POOL
- added error handling and cleanup in InitializeThreadpool
When a hdc is created no initial or default objects are created
therefore can the first call of gdi_SelectObject return NULL.
Because of this checking the return value of gdi_SelectObject failed
for newly create hdc causing errors (disconnects).
Since all types of HGDIOBJECT are handled and the return value of
gdi_SelectObject isn't used the recently added checks were removed
again.
rfx_process_message_sync:
- simplified the check if the header messages got processed
rfx_process_message_tileset:
- ObjectPool_Take result was not checked
- fail if TS_RFX_TILE block type is not CBT_TILE
- CreateThreadpoolWork result was not checked
- post decoding loop code segfaulted in error case
rfx_decoder_tile_new:
- missing malloc check
rfx_message_free:
- segfault protection
rfx_write_message_tileset:
- segfault protection
- removed some unneeded null checks for free()
- fixed a memory leak in shadow_client
- removed rfx_compose_message_header from API
Changed the following functions to BOOL, check the result
where they are called and handle failures:
- rfx_compose_message
- rfx_compose_message_header
- rfx_write_tile
- rfx_write_message_tileset
- rfx_write_message_frame_begin
- rfx_write_message_region
- rfx_write_message_frame_end
- rfx_write_message
rfx_process_message:
- check memory allocation failures
- verify protocol-conform order of data messages to prevents memory
leaks caused by repeated allocations
- verify that header messages were parsed/received before the
data messages
- treat unknown rlgr mode as error
- fixed/added error handling
- fixed all callers to check/handle result
rfx_encode_message:
- fixed incorrect usage of realloc
- missing malloc check
- missing check of CreateThreadpoolWork
- correct cleanup on failure (threadpool, memory)
- check rfx_encode_message result
rfx_encode_messages:
- check rfx_split_message result
- correct cleanup on failure
- prevent memory leak on failure
rfx_write_message_context:
- fixed invalid channelId value (must be 0xFF for WBT_CONTEXT)
rfx_process_message_codec_versions:
- fixed invalid read size of codec_version (it is 16bit)
rfx_process_message_channels:
- verify protocol conform channelId value
rfx_process_message_region:
- replaced invalid reallocs with malloc
- read and verify regionType and numTileSets from stream
rfx_process_message_tileset:
- check allocation results
- fixed incorrect usages of realloc
setupWorkers:
- fixed incorrect usages of realloc
rfx_split_message:
- removed dead code
- missing malloc check
rfx_compose_message:
- fixed a memory leak
- check/handle rfx_encode_message result
* top level GDI functions return 0 on error and != 0 otherwise but the
low level functions (16bpp.c, 8bpp.c 32bpp.c) which are called did it
exactly the other way around. Those were adapted.
* change gdi_InvalidateRegion to BOOL and check calls where appropriate
* integrate comments from pull request
