- Cleanup the /lib directory, by putting more 3rd-party libs in /3rdparty, and by creating a new directory called /sdk where libraries which emulate the ones in the WDK are present (Such as uuid, nt, crt, etc).

- Removed lib/interlck and lib/string.
- Removed math routines from lib/rtl.
- Created a new library called libcntpr which is what NT/WDK use when compiling the kernel/system libraries. This is an "NT-Private" version of the CRT which is supposed to contain what we had in lib/string and lib/rtl.
