TurboJPEG: New param to limit virt array mem usage

Browse Source 
This corresponds to max_memory_to_use in the jpeg_memory_mgr struct in
the libjpeg API, except that the TurboJPEG parameter is specified in
megabytes.  Because this is 2023 and computers with less than 1 MB of
memory are not a thing (at least not within the scope of libjpeg-turbo
support), it isn't useful to allow a limit less than 1 MB to be
specified.  Furthermore, because TurboJPEG parameters are signed
integers, if we allowed the memory limit to be specified in bytes, then
it would be impossible to specify a limit larger than 2 GB on 64-bit
machines.  Because max_memory_to_use is a long signed integer,
effectively we can specify a limit of up to 2 petabytes on 64-bit
machines if the TurboJPEG parameter is specified in megabytes.  (2 PB
should be enough for anybody, right?)

This commit also bumps the TurboJPEG API version to 3.0.1.  Since the
TurboJPEG API version no longer tracks the libjpeg-turbo version, it
makes sense to increment the API revision number when adding constants,
to increment the minor version number when adding functions, and to
increment the major version number for a complete overhaul.

This commit also removes the vestigial TJ_NUMPARAM macro, which was
never defined because it proved unnecessary.

Partially implements #735

@@ -10,6 +10,16 @@ triggered by setting the `align` parameter to an unreasonably large value.
This issue did not pose a security threat, but removing the warning made it
easier to detect actual security issues, should they arise in the future.
2. Introduced a new parameter (`TJPARAM_MAXMEMORY` in the TurboJPEG C API and
`TJ.PARAM_MAXMEMORY` in the TurboJPEG Java API) and a corresponding TJBench
option (`-maxmemory`) for specifying the maximum amount of memory (in
megabytes) that will be allocated for intermediate buffers, which are used with
progressive JPEG compression and decompression, optimized baseline entropy
coding, lossless JPEG compression, and lossless transformation. The new
parameter and option serve the same purpose as the `max_memory_to_use` field in
the `jpeg_memory_mgr` struct in the libjpeg API, the `JPEGMEM` environment
variable, and the cjpeg/djpeg/jpegtran `-maxmemory` option.
