Include namespace.h in GCDAProfiling.c (compiler_rt)

The NetBSD Standard C Library uses internally some of its functions with
a mangled symbol name, usually "_symbol". The internal functions shall not
use the global (public) symbols.

This change eliminates usage of the global name of the following symbols:
- fdopen -> _fdopen
- mmap -> _mmap
- strdup -> _strdup

Revert namespacing of atoi(3)

Sanitizers can handle recursive interceptions in some / most cases, if they
will cause damage the problem will be not workaroundable without libc
changes - I will be back to it.

Keep namespace of asctime() as this can be a cancellation point according
to POSIX. Right now it's not implemented on NetBSD. Defer it for later.

Keep weak symbols and namespace for wait6(2) as this could be a
cancellation point as well. Defer this for later.

Sanitizers's [recursive] interceptors are a hack and moving one way or
another can cause new sets of problems. Recursive ones can be useful and
cause problems (on Linux there are known with with signal handlers).

Register new weak symbol in libc for internal usage: atoi

The NetBSD Standard C Library uses internally some of its functions with
a mangled symbol name, usually "_symbol". The internal functions shall not
use the global (public) symbols.

Add atoi to namespace.h.

Register a new __weak_alias() entry for atoi() in atoi.c.

atoi() is used internally in getrpcent(), rresvport_af(), ftok(), err(),
__llvm_profile_write_file(), llvm_gcda_start_file(), citrus_iconv_open(),
getprotoent_r(), __rpc_uaddr2taddr_af(), __res_nopt_rdata() and
servent_parseline().

This revision switches the internal usage to the internal symbol.
