This avoids taking quadratic time to pretty-print certificates with
excessively large integer fields. Very large integers aren't any more
readable in decimal than hexadecimal anyway, and the i2s_* functions
will parse either form.

This guards against the name constraints check consuming large amounts
of CPU time when certificates in the presented chain contain an
excessive number of names (specifically subject email names or subject
alternative DNS names) and/or name constraints.
Name constraints checking compares the names presented in a certificate
against the name constraints included in a certificate higher up in the
chain using two nested for loops.
Move the name constraints check so that it happens after signature
verification so peers cannot exploit this using a chain with invalid
signatures. Also impose a hard limit on the number of name constraints
check loop iterations to further mitigate the issue.
Thanks to NCC for finding this issue.

Instead of a script which generates macros, emit static inlines in
individual header (or C files). This solves a few issues with the
original setup:
- The documentation was off. We match the documentation now.
- The stack macros did not check constness; see some of the fixes in
crypto/x509.
- Type errors did not look like usual type errors.
- Any type which participated in STACK_OF had to be made partially
public. This allows stack types to be defined an internal header or
even an individual file.
- One could not pass sk_FOO_free into something which expects a function
pointer.

that suppressed warnings on a per-function basis no longer work in

MSVC 2013 as MSVC 2013 doesn't support "%zu". Finally, Update 1 has new
warnings, some of which need to be suppressed.

Updated by davidben to give up on suppressing warnings in crypto/x509 and
crypto/x509v3 as those directories aren't changed much from upstream. In each
of these cases, upstream opted just blindly initialize the variable, so do the
same. Also switch C4265 to level 4, per Microsoft's recommendation and work
around a bug in limits.h that happens to get fixed by Google include order
style.
(limits.h is sensitive to whether corecrt.h, pulled in by stddef.h and some
other headers, is included before it. The reason it affected just one file is
we often put the file's header first, which means base.h is pulling in
stddef.h. Relying on this is ugly, but it's no worse than what everything else
is doing and this doesn't seem worth making something as tame as limits.h so
messy to use.)

It's very annoying having to remember the right incant every time I want
to switch around between my build, build-release, build-asan, etc.,
output directories.
Unfortunately, this target is pretty unfriendly without CMake 3.2+ (and
Ninja 1.5+). This combination gives a USES_TERMINAL flag to
add_custom_target which uses Ninja's "console" pool, otherwise the
output buffering gets in the way. Ubuntu LTS is still on an older CMake,
so do a version check in the meantime.
CMake also has its own test mechanism (CTest), but this doesn't use it.
It seems to prefer knowing what all the tests are and then tries to do
its own output management and parallelizing and such. We already have
our own runners. all_tests.go could actually be converted tidily, but
generate_build_files.py also needs to read it, and runner.go has very
specific needs.
Naming the target ninja -C build test would be nice, but CTest squats
that name and CMake grumps when you use a reserved name, so I've gone
with run_tests.
