fix [client channels]: move exported API calls to client/common

The functions mappedGeometryRef and mappedGeometryUnref are API
functions ([1]) but were implemented in the geometry channel.
In case FreeRDP was built with BUILTIN_CHANNELS=OFF those functions
weren't available globally but used by the video channel.

Now the functions are fixed part of the freerdp-client library and
therefore available for all channels.

[1] exported in freerdp/client/geometry.h

uwac: don't try to use O_TMPFILE on FreeBSD

Currently, this sets an invalid open flag and attempts to open(), which
will fail.  Instead of doing that, don't try to define O_TMPFILE where
such a definition can't exist and force the fallback rather than making
an always-fail open() call.

winpr/library: Use RTLD_GLOBAL for dlopen

LoadLibraryA implementation uses the RTLD_LOCAL flag for dlopen currently.
This flag doesn't allow the symbols to be used by the subsequently loaded
libraries. This is a problem for the video channel when -DBUILTIN_CHANNELS=OFF
is used as it uses functions from the geometry channel. Let's use RTLD_GLOBAL
instead to prevent "undefined symbol" errors in such cases.
