This patch moves safe_strerror from the gdb/{posix,mingw}-hdep.c files
to the respective common/{posix,mingw}-strerror.c files. This is a
preparation for the next patch, which shares a common code (to disable
address space randomization when creating a new inferior).
The patch has been regtested on Fedora 20 x86_64, and no regressions
were found.
