development headers for libaxc

 Client library for libsignal-c, implementing the needed database and crypto
 interfaces using SQLite and gcrypt. Initially, the library's name was
 libaxolotl, hence the name.
 .
 Additionally it provides utility functions for common use cases like encrypting
 and decrypting, ultimately making direct use of libsignal unnecessary.
 .
 This package contains the development files.
