svn commit: r337938 - head/sys/crypto/libsodium

[Conrad Meyer]

Author: cem

New Revision: 337938
URL: https://svnweb.freebsd.org/changeset/base/337938

Log:
  Bring in compatibility glue for libsodium
  
  The idea is untouched upstream sources live in sys/contrib/libsodium.
  
  sys/crypto/libsodium are support routines or compatibility headers to allow
  building unmodified upstream code.
  
  This is not yet integrated into the build system, so no functional change.
