Provide backward compatibility layer for deprecated functions.

* include/mailutils/sieve.h (mu_sieve_compile_text): New proto.
(mu_sieve_compile_buffer): Backward-compatible proto.
* include/mailutils/stream.h ((MU_IOCTL_LOGSTREAM_GET_LOCUS_DEPRECATED)
(MU_IOCTL_LOGSTREAM_SET_LOCUS_DEPRECATED): New defines.
(MU_IOCTL_LOGSTREAM_GET_LOCUS)
(MU_IOCTL_LOGSTREAM_SET_LOCUS): Use external functions to make
sure any references to these are marked as deprecated.
* include/mailutils/types.hin (mu_locus_DEPRECATED): New struct.
(mu_locus): Define to mu_locus_DEPRECATED
* libmailutils/stream/logstream.c (_log_ctl): Handle the deprecated
ctls.
* libmu_sieve/extensions/moderator.c (moderator_filter_message): Use
mu_sieve_compile_text.
* libmu_sieve/sieve-gram.y (mu_sieve_compile_buffer): Rename to
mu_sieve_compile_text.  Re-introduce it as a backward-compatibility
API.
* sieve/sieve.c: Call mu_sieve_compile_text instead of
mu_sieve_compile_buffer.
