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.

Don't use |BIO_set_foo_buffer_size| when setting the
sizes of the buffers while making buffer pair. Since it
happens in pair.c we know the BIOs are BIO pairs and using
bio_ctrl here complicates setting external buffers. Also
zero out bio_bio_st during construction.

This fixes a problem that would happen if the default buffer
sizes were not set, since buf_externally_allocated was
not yet initialized.

Remove BIO_C_SET_BUFF_SIZE and BIO_CTRL_RESET which are
not used for bio pairs.

Also add functionality for setting external buffers to give the
caller better control of the buffers. This is typical needed if OS
sockets can outlive the bio pair.
