Import BoringSSL's crypto bytestring and crypto bytebuilder APIs.

This is imported with as few changes as possible for the initial commit.
I removed OPENSSL_EXPORT, replaced OPENSSL_malloc() etc with malloc()
and changed a few header includes.

BoringSSL has this as part of their public API.  We're leaving it internal
to libssl for now.

Based on BoringSSL's CBB/CBS API as of commit
c5cc15b4f5b1d6e9b9112cb8d30205a638aa2c54.
