This has been requested a few times over the years. This is basically
a very late rebase of https://android-review.googlesource.com/45470
which was abandoned years ago. One addition is that this version has
_FILE_OFFSET_BITS=64 support.
POSIX puts this in <unistd.h>. glibc also has it in <fcntl.h>.

This is just a subset of the recently-implemented getifaddrs(3), though if
we want to handle interfaces (such as "rmnet_*") that don't have an address,
we need to either expose ifaddrs_storage and keep track of which interfaces
we've already seen (which is pretty messy), or refactor the netlink code so
we can reuse it and just extract the information we need for if_nameindex(3).
This patch goes the latter route.
Also clean up if_nametoindex(3) and if_indextoname(3).

We had these symbols incorrectly versioned as LIBC_PRIVATE
in M release. This change moves __aeabi* symbols from LIBC
to LIBC_N and adds __gnu_Unwind_Find_exidx to the list

bzero is hashdefined to memset in strings.h and it
was removed from POSIX 2008.

The following arm symbols should be exported by libc.so:
__aeabi_atexit; # arm
__aeabi_memclr; # arm
__aeabi_memclr4; # arm
__aeabi_memclr8; # arm
__aeabi_memcpy; # arm
__aeabi_memcpy4; # arm
__aeabi_memcpy8; # arm
__aeabi_memmove; # arm
__aeabi_memmove4; # arm
__aeabi_memmove8; # arm
__aeabi_memset; # arm
__aeabi_memset4; # arm
__aeabi_memset8; # arm

This reverts commit 76814a8250.
This differs from the original in fixing the GCC -Werror build:
bionic/libc/bionic/ifaddrs.cpp: In function 'void __handle_netlink_response(ifaddrs**, nlmsghdr*)':
bionic/libc/bionic/ifaddrs.cpp:113:62: error: use of old-style cast [-Werror=old-style-cast]
ifinfomsg* ifi = reinterpret_cast<ifinfomsg*>(NLMSG_DATA(hdr));
This appears to be a GCC bug; the GCC command-line correctly uses -isystem,
and manually adding #pragma GCC system_header doesn't help. So just turn the
warning off for GCC for now. We won't need to worry about building with GCC
soon anyway.

Brillo doesn't use the ndk cruft, so we need
separate set of version scripts. Added new "nobrillo"
tag to mark such symbols in *.map.txt files.
