* Add rerun-if-env-changed instructions for BORING_* variables
* Use X509_get0_notBefore() and X509_get0_notAfter() instead of X509_getm_notBefore() and X509_getm_notAfter().
According to
https://www.openssl.org/docs/man1.1.0/man3/X509_getm_notBefore.html,
"X509_getm_notBefore() and X509_getm_notAfter() are similar to
X509_get0_notBefore() and X509_get0_notAfter() except they return
non-constant mutable references to the associated date field of the
certificate".
* Only update boringssl submodule if BORING_BSSL_PATH not provided
* Allow BORING_BSSL_LIB_PATH to control link search
* Add fips feature
* Use X509_set_notAfter unconditionally for FIPS compatibility
This is equivalent according to
https://boringssl.googlesource.com/boringssl/+/c947efabcbc38dcf93e8ad0e6a76206cf0ec8072
The version of boringssl that's FIPS-certified doesn't have `X509_set1_notAfter`.
The only difference between that and `X509_set_notAfter` is whether they're const-correct,
which doesn't seem worth having two different code-paths.
* Check out fips commit automatically
* Verify the version of the compiler used for building boringssl
NIST specifies that it needs to be 7.0.1; I originally tried building with clang 10 and it failed.
Theoretically this should check the versions of Go and Ninja too, but they haven't given me trouble in practice.

error: failed to run custom build command for `openssl-sys v0.9.13`
run pkg_config fail: "Failed to run `\"pkg-config\" \"--libs\" \"--cflags\" \"openssl\"`: No such file or directory (os error 2)"
Problem encountered on WSL (Ubuntu on windows).
Fixed by installing pkg-config
Prior to this commit in 43c951f743 the
ability to pass OPENSSL_LIBS was removed from the build.rs of
openssl-sys. This commit adds the ability to pass custom names for the
OPENSSL_LIBS back in. This is useful for when building openssl across
linux and windows with the same lib names (ssl:crypto) and the default
names provided by the build script are not valid.
The slproweb.com OpenSSL distribution does not contain root certificates, so they need to be downloaded and installed manually to avoid certificate warnings when making requests.
