[ Alexey Spiridonov ]
* mtbl_reader(3): New reader getters, which expose the values stored
in the "metadata" (formerly "trailer") at the end of MTBL files. For
example: the number of bytes of source data in the keys & values is
available via mtbl_metadata_bytes_keys() & mtbl_metadata_bytes_values().
* mtbl_writer(3): Allow foreign data to be written to the beginning of a
file before its file descriptor is passed to mtbl_writer_init_fd().
[ Robert Edmonds ]
* Add mtbl_verify(1) utility which verifies the embedded data and index
block checksums in an MTBL file.
* Stop keeping dup()'d copies of the file descriptors passed to
mtbl_reader_init_fd(). POSIX does not require a process to keep an open
file descriptor corresponding to an mmap()'d file. This change allows a
process to open more MTBL files than the process file descriptor limit.
* mtbl_dump(1): Add silent ("-s") option which omits the actual dump output.
This is useful when benchmarking decompression performance.
* Add LZ4/LZ4HC compression support. This adds a new library dependency on
liblz4.
* mtbl_merge(1): Add block size ("-b") and compression algorithm ("-c")
options.
* mtbl_fileset(3): Add mtbl_fileset_reload_now() function that
instantaneously checks and, if necessary, reloads the fileset.
