The logic to reset *pp doesn't actually work if pp is NULL. (It also doesn't
work if *pp is NULL, but that didn't work before either.) Don't bother
resetting it. This is consistent with the template-based i2d functions which do
not appear to leave *pp alone on error.

If we're to allow the buggy CPU workaround to fire when __ARM_NEON__ is set,

Chromium uses GN's default configs feature which makes all targets default to a
set of configs. It then expects third_party code to take one of them
(chromium_code) out and put in a different one (no_chromium_code).
Because of that, we need a way to tell the template to emit -= lines. Add a
separate option for that.
(It may be worth making us clean against the chromium_code config rather than
the no_chromium_code one, but I'll explore that separately in case making the C
code clean ends up being a rabbithole.)

The getauxval (and friends) code would be filling that in anyway. The default
only serves to enable NEON even if the OS is old enough to be missing getauxval
(and everything else).
Notably, this unbreaks the has_buggy_neon code when __ARM_NEON__ is set, as is
the case in Chrome for Android, as of M50. Before, the default
OPENSSL_armcap_P value was getting in the way.
Arguably, this doesn't make a whole lot of sense. We're saying we'll let the
CPU run compiler-generated NEON code, but not our hand-crafted stuff. But, so
far, we only have evidence of the hand-written NEON tickling the bug and not
the compiler-generated stuff, so avoid the unintentional regression. (Naively,
I would expect the hand-crafted NEON is better at making full use of the
pipeline and is thus more likely to tickle the CPU bug.)
This is not the fix for M50, as in the associated Chromium bug, but it will fix
master and M51. M50 will instead want to revert

Due to Android's complex branching scheme, we have to keep building against a
snapshotted version of wpa_supplicant. wpa_supplicant, in preparation for
OpenSSL 1.1.0, added compatibility versions of some accessors that we, in
working towards opaquification, have imported. This causes a conflict (C does
not like having static and non-static functions share a name).
Add a hack in the headers to suppress the conflicting accessors when
BORINGSSL_SUPPRESS_ACCESSORS is defined. Android releases which include an
updated BoringSSL will also locally carry this #define in wpa_supplicant build
files. Once we can be sure releases of BoringSSL will only see a new enough
wpa_supplicant (one which includes a to-be-submitted patch), we can ditch this.
