is triggered on `-v`.

ad344033df Fix broken assertion 
The `avgJobSize` must not be lower than 256 KB for single-pass mode.
In `zstd.h` we say the minimum value for `ZSTD_p_jobSize` is 1 MB,
so ensure that we always pick a size >= 1 MB.

Found by libFuzzer fuzzer tests with large input limits.

153bc1c004 removed limit ZSTD_TARGETLENGTH_MAX 
this makes it possible to specify extremely large negative compression levels,
achieving the side effect as "no compression".

It will also be possible to define larger targetlength for ultra compression mode.

There is no adverse side effect due to removing this limit.

136b9e2392 Fix external sequence corner cases 
* Clear external sequences when we reset the `ZSTD_CCtx`.

to accept a dictContentType parameter (raw, full, auto).

94c77710a9 Integrate ldm with zstdmt 
Integrate ldm into zstdmt by running it in serial and in order in the first
step of each job, in the same place as the hash gets updated. The input
buffer is sized to fit the whole LDM window and 2 full buffers of slack.
Input buffers cannot be reused until the LDM step is done with them.
After the LDM step is finished, the jobs don't actually have access to the
full window, only the overlap.

Tested on a few different multi-GB files with and without sanitizers,
and with different numbers of threads.
