added a uid_wrapper library This library intercepts seteuid and related calls, and simulates them in a manner similar to the nss_wrapper and socket_wrapper libraries. This allows us to enable the vfs_unixuid NTVFS module in the build farm, which means we are more likely to catch errors in the token manipulation. The simulation is not complete, but it is enough for Samba4 for now. The major areas of incompleteness are: - no emulation of setreuid, setresuid or saved uids. These would be needed for use in Samba3 - no emulation of ruid changing. That would also be needed for Samba3 - no attempt to emulate file ownership changing, so code that (for example) tests whether st.st_uid matches geteuid() needs special handling

s4:UID wrapper - Make it work on older distributions On my older CentOS 4 installation I had the problem with the missing substitution prototypes ("uwrap_*"). So I added them to "uid_wrapper.h". Also, I made the head of the "uid_wrapper.c" file more like the one of "nss_wrapper.c" - it shouldn't change that much, I did it only to be consistent. This patch should fix the build on older distributions while keep it running on newer ones.
