Missing include required to build in OS X

[mrmekon]

Problem
Current git tip fails to build on OS X because of an unknown identifier (fd_set) in rdpdr_main.h:60

Steps to reproduce

# git clone https://github.com/FreeRDP/FreeRDP.git
# cd FreeRDP/
# sh autogen.sh 
# ./configure
# make

Expected result
No error, built executable

Actual Result

Making all in channels/rdpdr
  CC     rdpdr_la-rdpdr_main.lo
  CC     rdpdr_la-rdpdr_capabilities.lo
  CC     rdpdr_la-devman.lo
In file included from rdpdr_scard.h:28,
                 from devman.c:25:
rdpdr_main.h:60: error: expected specifier-qualifier-list before 'fd_set'
make[2]: *** [rdpdr_la-devman.lo] Error 1
make[1]: *** [all-recursive] Error 1
make: *** [all] Error 2

Proposed solution
Including select.h in rdpdr_main.h solved the problem. Patch below:

diff --git a/channels/rdpdr/rdpdr_main.h b/channels/rdpdr/rdpdr_main.h
index 5180347..a4b67c8 100644

@awakecoding it seems you have OSX at hand. Could you check this issue?

rdpdr_main.h wasn't including sys/select.h which defines fd_set on Mac OS X. issue fixed and pushed on git.
