[PATCH 0/2] help: include SHA build options in version info

Greetings,

Additional information regarding how Git was build can be found via the `--build-options` flag for git-verison(1). This currectly does not include information about the SHA-1 and SHA-256 implementations Git is built with.

This short series adds build option info for the SHA-1, SHA-256, and unsafe-SHA-1 (if any) implementations which may be useful for diagnostic purposes.

Regarding "unsafe-SHA-1", I wonder if we should use a different name in the printed build options that sounds a little less scary. I was thinking maybe "fast-SHA-1" and document its meaning appropriately. I'm interested to know if anyone has thoughts on this.

Thanks, -Justin
