Hash : c9675a23
Message : Make internal header file names consistent Libcrypto currently has a mess of *_lcl.h, *_locl.h, and *_local.h names used for internal headers. Move all these headers we inherited from OpenSSL to *_local.h, reserving the name *_internal.h for our own code. Similarly, move dtls_locl.h and ssl_locl.h to dtls_local and ssl_local.h. constant_time_locl.h is moved to constant_time.h since it's special. Adjust all .c files in libcrypto, libssl and regress. The diff is mechanical with the exception of tls13_quic.c, where #include <ssl_locl.h> was fixed manually. discussed with jsing, no objection bcook
