17cf2cb1d2 Work around language and compiler bug in memcpy, etc.
Most C standard library functions are undefined if passed NULL, even
when the corresponding length is zero. This gives them (and, in turn,
all functions which call them) surprising behavior on empty arrays.
Some compilers will miscompile code due to this rule. See also
https://www.imperialviolet.org/2016/06/26/nonnull.html

Add OPENSSL_memcpy, etc., wrappers which avoid this problem.

BUG=23

f0bba61663 Fix ASN1_INTEGER handling.
Only treat an ASN1_ANY type as an integer if it has the V_ASN1_INTEGER
tag: V_ASN1_NEG_INTEGER is an internal only value which is never used
for on the wire encoding.

(Imported from upstream's d4b25980020821d4685752ecb9105c0902109ab5.)

This is redundant with our fb2c6f8c85 which I
think is a much better fix (having two notions of "type" depending on whether
we're in an ASN1_TYPE or an ASN1_STRING is fragile), so I think we should keep
our restriction too. Still, this is also worth doing.

57707c70dc OpenSSL reformat x509/, x509v3/, pem/ and asn1/.
OpenSSL upstream did a bulk reformat. We still have some files that have
the old OpenSSL style and this makes applying patches to them more
manual, and thus more error-prone, than it should be.

This change is the result of running
  util/openssl-format-source -v -c .
in the enumerated directories. A few files were in BoringSSL style and
have not been touched.

This change should be formatting only; no semantic difference.

2b2d66d409 Remove string.h from base.h.
Including string.h in base.h causes any file that includes a BoringSSL
header to include string.h. Generally this wouldn't be a problem,
although string.h might slow down the compile if it wasn't otherwise
needed. However, it also causes problems for ipsec-tools in Android
because OpenSSL didn't have this behaviour.

This change removes string.h from base.h and, instead, adds it to each
.c file that requires it.
