e754c6bbb7 Having decided not to provide a libmemstat(3) error number to text
conversion routine, now change my mind and add one, memstat_strerror(3),
which returns a const char * pointer to a string describing the error,
to be used on the results of memstat_mtl_geterror().

While here, also correct a minor typo in the HISTORY man page.

Pointers on improving ease of internationalization would be
appreciated.

- Short description of each memory type access method.

- Descriptions of libmemstat(3) errors and memstat_mtl_geterror(3).

0cddce4989 Add libmemstat(3), a library for use by debugging and monitoring
applications in tracking kernel memory statistics.  It provides an
abstracted interface to uma(9) and malloc(9) statistics, wrapped
around the recently added binary stream sysctls for the allocators.

Using this interface, it is easy to build monitoring tools, query
specific memory types for usage information, etc.  Facilities are
provided for binding caller-provided data to memory types,
incremental updates of memory types, and queries that span multiple
allocators.

Support for additional allocators is (relatively) easy to add.

The API for libmemstat(3) will probably change some over time as
consumers are written, and requirements evolve.  It is written to
avoid encoding ABIs for data structure layout into consuming
applications for this reason.
