Extend winpr and client/common to support a new option "/buildconfig".
When used build the following build specific information is print:
* cmake options
* cflags
* compiler
* target architecture
* cmake build type
Visual Studio 2010 use a compiler that supports only C89, which
only supports declaring variable at top of a local scope. Moving
scope variable to the top of function should solve this problem.
Don't set the identifier to "winpr" as default value because journald
will use the programs name as default if no identifier is set.
This way a program using WLog doesn't need to set an identifier (except
it want something different then it's name).
* only expose necessary functions and types in header
* don't expose appender internals
* add generic function WLog_ConfigureAppender to have the possibility
to configure appender specific settings
* detect appender availability if WLog_SetLogAppenderType or
WLog_Appender_New return FALSE or NULL respectively the appender isn't
available or the initialization failed. This is very useful for the
use with optional appenders.
* add Free to the appender interface. At the time of the Free the
appender is known and available so it can be called directly (instead
of calling the right function according to the type)
* make all appender internal function static
* all appenders return the generic wLogAppender type now. Typecasts
are internally done where necessary this abstracts the appenders more
cleanly
This appender allows to receive the logs over a network connection using UDP packets.
You can see the logs using a listening netcat, for example: nc -ul 127.0.0.1 20000.
winpr/libwinpr/utils/wlog/wlog.c: In function ‘WLog_PrintMessageVA’:

wlog used to return an int but the only meaning
of the return value was:
* negative ... error
* 0 or positive ... success
but the positve returned value was 1 or some id of some
subsystem, nothing meaningful for the caller.
For a more meaningful returnvalue we now use BOOL.
If something goes wrong FALSE is returned.
