Our fopen/freopen/tmpfile are already always O_LARGEFILE, but let's add
the aliases for _LARGEFILE_SOURCE compatibility.

585e959849 Generate libc version-script for brillo
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.

ac77536b79 Move tzdata scripts from bionic to external/icu
The scripts affect files in external/icu, bionic
and the generated files affect libcore. The files must
be updated together so there is no "obvious" home.

OEM developers seem to want to update ICU
themselves and have been asking how. Moving the
scripts to external/icu and splitting the ICU generation
code into a sub-script they can run makes some sense.

4d3abcb033 Update update-tzdata.py tool to generate ICU4J data jars
The ICU4J changes are not necessary for use on Android (since
we use the ICU4C .dat file), but updating them ensures that
the .jars in sync with everything else and the jars are currently
required for host tests.

00490ae3f3 Ensure raw fchmod/fchmodat syscalls are hidden.
In https://android-review.googlesource.com/#/c/127908/5/libc/SYSCALLS.TXT@116
Elliott said:

  for LP64 these will be hidden. for LP32 we were cowards and left
  them all public for compatibility (though i don't think we ever
  dremeled to see whether it was needed). we don't have an easy
  way to recognize additions, though, so we can't prevent adding
  new turds.

Add a mechanism to prevent the adding of new turds, and use that
mechanism on the fchmod/fchmodat system calls.

9c3fd59b00 Add a basic NDK compatibility library.
We know we can safely statically link `libm`, since it doesn't have
any dependencies on the OS or the layout of a data type that has
changed between releases (like `pthread_t`).

We can safely statically link `libc_syscalls` because the user can
check for and handle `ENOSYS`.

Update `ndk_missing_symbols.py` to account for symbols that are in the
compatibility library.

Improve `symbols.py` to be able to pull symbols from a static library.

0393221f47 Make the missing symbols script more useful.
If something's in POSIX, we don't need to show it in the glibc list.

If something's not implemented by glibc, we don't need to show it in the
POSIX list (because it's probably either a macro or obsolete).

2c2463bd30 Fix tzdata update tools for 'backzone'.
To maintain the status quo, we need to pull in backzone file. This file
can't be built on its own, so the easiest fix is to give zic(1) all the
files at once.

We also now have a situation where we have links to links, so we need to
dereference them until we find actual data.

6869d26ad9 Force export symbols on all x86 variants in libc.
For silvermont, the __popcountsi2 symbol does not get exported by libc.
But for atom, this symbol is exported. Since we already exported this symbol
for previous releases, it's better to just follow through and force
the export, but only for 32 bit. x86 64 bit will not export this symbol.

011e111d29 Ensure __set_errno is still visible on LP32.
The use of the .hidden directive to avoid going via the PLT for
__set_errno had the side-effect of actually making __set_errno
hidden (which is odd because assembler directives don't usually
affect symbols defined in a different file --- you can't even
create a weak reference to a symbol that's defined in a different
file).

This change switches the system call stubs over to a new always-hidden
__set_errno_internal and has a visible __set_errno on LP32 just for
binary compatibility with old NDK apps.

76212eeb53 Add more functionality to glibc symbol checker.
Also scan NDK's unwanted symbols list (to show the things that we're
exporting but the NDK isn't. Symbols hidden in the NDK will be marked
with a *.

Add a -u (--unwanted) flag to disable the first two printed groups
(all symbols in bionic, all symbols in glibc). This is helpful when
wanting to grep in the list of unwanted symbols.

Finally, update the list of known differences between us and glibc.

01bd32e0e4 Create a distinct temp directory for each run.
Modify make__NR_name so that only __ARM_NR_ is exempted from the
__NR_ being prepended. This avoids a case where using a name starting
with __ but is not a valid syscall name in SYSCALLS.TXT does not generate
code that will compile but references the function itself and causes
link errors.

Fix all of the directory references from dir_part1 + dir_part2 to
use os.path.join() instead.

13bab43337 Fix the tzdata update tools.
The recent libcore ZoneInfo changes mean that we can no longer
compile libcore's ZoneInfo against the RI. Luckily, the field in
our data file that we needed ZoneInfo for isn't actually used.
This change removes our dependence on libcore.

I've left the field in to avoid a file format change. We can remove
the field if/when we next have a real need to bump the file format.
