Subject: style: util.[ch]: Introduce hex_encode_alloc name
X-Git-Url: https://www.chiark.greenend.org.uk/ucgi/~mdw/git/secnet/commitdiff_plain/36a81f9cfda6df8a79169e93a251e8e13b64f09c?hp=36a81f9cfda6df8a79169e93a251e8e13b64f09c

style: util.[ch]: Introduce hex_encode_alloc name

Prompted by review of 7be31e47b2a8
  "util.[ch]: Factor out hex encoding and decoding utilities."
which says
  The interface is a bit odd, but it will fit with the uses
  I have in mind.

Not sure if it's the encode or decode interface which is referred to.
Certainly there should be a non-allocating variant.  I decided to
rename the allocating one.

The two separate buffer arguments to hex_decode are indeed a bit odd
but IMO tolerable.
