This commit also allows `memfd_create` in the seccomp-bpf policy for all
process types.
`memfd_create` is an API added in Linux 3.17 (and adopted by FreeBSD
for the upcoming version 13) for creating anonymous shared memory
not connected to any filesystem. Supporting it means that sandboxed
child processes on Linux can create shared memory directly instead of
messaging a broker, which is unavoidably slower, and it should avoid
the problems we'd been seeing with overly small `/dev/shm` in container
environments (which were causing serious problems for using Firefox for
automated testing of frontend projects).
`memfd_create` also introduces the related operation of file seals:
irrevocably preventing types of modifications to a file. Unfortunately,
the most useful one, `F_SEAL_WRITE`, can't be relied on; see the large
comment in `SharedMemory:ReadOnlyCopy` for details. So we still use
the applicable seals as defense in depth, but read-only copies are
implemented on Linux by using procfs (and see the comments on the
`ReadOnlyCopy` function in `shared_memory_posix.cc` for the subtleties
there).
There's also a FreeBSD implementation, using `cap_rights_limit` for
read-only copies, if the build host is new enough to have the
`memfd_create` function.
The support code for Android, which doesn't support shm_open and can't
use the memfd backend because of issues with its SELinux policy (see bug
1670277), has been reorganized to reflect that we'll always use its own
API, ashmem, in that case.

I haven't been able to confirm that this would actually fix
`--with-system-icu`, but since the new regexp
engine (`js/src/new-regexp`) explicitly includes this file and this file
isn't already present in system-headers...it seems very likely that this
change will fix `--with-system-icu`.

"disjunction" and "unit" types aren't yet supported, because ICU doesn't
provide a C-API for this functionality. "short" and "narrow" styles aren't
supported for the same reason.

- Add NumberFormatterSkeleton as a helper class to construct a number formatter
skeleton. When the "Intl.NumberFormat Unified API" proposal gets implemented
a more feature-rich class may be necessary.
- In addition to a UNumberFormatter instance, NumberFormatObject now also
stores a UFormattedNumber instance. This avoids a performance regression
compared to creating a new UFormattedNumber object each time a number gets
formatted. (In micro-benchmarks 20% regressions were seen, with a cached
UFormattedNumber the same micro-benchmarks even improved by ~33%.)
- Add accessors for reserved slot values to NumberFormatObject to improve
readibility.

Enough linux-based systems don't have libsecret that we can't make it a
requirement on linux. For those that do, however, we can dynamically load the
library at runtime. For those that don't, we can fall back to NSS.

This implements an API in `nsIOSKeyStore.idl` and `OSKeyStore.cpp` to encrypt and decrypt bytes with a key that is stored in the OS key store.
There are two OS adapters in this patch.
Libsecret is used on Linux if available.
The NSS key store is used as fallback if no OS specific key store is implemented.

Our bundled Hunspell now significantly differs from upstream Hunspell. Most
importantly, it supports loading dictionaries from jar: URIs, which is now a
requirement for loading bundled and extension dictionaries. This means that
system Hunspell libraries are no longer compatible with our spell checker
code. We should remove the option to use them so that users don't fall into
the trap of trying to use them.

Fix several problems when building Breakpad with new NDK unified
headers.
- Unified headers define its own tgkill wrapper, so rename our own
wrapper to __tgkill.
- Unified headers define user_fpxregs_struct for all API levels, so
don't redefine it.
- Only the target sources under google-breakpad/src/common/linux should
use custom Android headers, so change the includes line in moz.build to
use OS_INCLUDES.
