Message:

Extending POSIX library

Merge from lp:~vojtech-horky/helenos/gcc-port.

This is work-in-progress merge from branch aimed at bringing GCC to run
inside HelenOS.

The most notable change is dealing with the name clashes in libposix and
libc. For ported applications, the libposix headers looks as normal
POSIX headers and there is no need to do preprocessor-based renaming inside
the ported application. The renaming is done inside object files instead.
See revision 1745 in lp:~vojtech-horky/helenos/gcc-port [1] for more
detailed explanation.
The solution is definitely not perfect but shall deal with the naming
conflicts in much safer manner than using the redefines.

There were some other changes as well, mostly small ones.

• Add some functions, some as ToDo ones (i.e. empty implementation).
• Add more POSIX headers, split some existing.
