ptsname_r on failure returns the value that is also set as errno; furthermore,
add more checks to it:
- set errno and return it on __term_get_peername failure
- set errno to ERANGE other than returning it
- change the type of PEERNAME to string_t, and check its length with __strnlen
In ptsname:
- change the type of PEERNAME to string_t
- do not set errno manually, since ptsname_r has set it already

When glibc is built with --enable-static-nss, the warning that
using NSS symbols requires the nss shared objects to be present
is no longer true, as those symbols are built into libc. Suppress
the warning for those symbols by providing a new macro
(nss_interface_function) for the NSS functions that is defined as
static_link_warning in the normal case, and empty for static NSS.

Using madvise with MADV_DONTNEED to release memory back to the kernel
is not sufficient to change the commit charge accounted against the
process on Linux. It is OK however, when overcommit is enabled or is
heuristic. However, when overcommit is restricted to a percentage of
memory setting the contents of /proc/sys/vm/overcommit_memory as 2, it
makes a difference since memory requests will fail. Hence, we do what
we do with secure exec binaries, which is to call mmap on the region
to be dropped with MAP_FIXED. This internally unmaps the pages in
question and reduces the amount of memory accounted against the
process.

mounted on /proc.
