b1ec94e63c Fix ZSTD_f_zstd1_magicless for small data 
* Fix `ZSTD_FRAMEHEADERSIZE_PREFIX` and `ZSTD_FRAMEHEADERSIZE_MIN` to
  take a `format` parameter, so it is impossible to get the wrong size.
* Fix the places that called `ZSTD_FRAMEHEADERSIZE_PREFIX` without
  taking the format into account, which is now impossible by design.
* Call `ZSTD_frameHeaderSize_internal()` with `dctx->format`.
* The added tests catch both bugs in `ZSTD_decompressFrame()`.

Fixes #1813.

50b9c41196 [libzstd] Fix decompression dictionary bugs and clean up initialization 
Bugs:

* `ZSTD_DCtx_refPrefix()` didn't clear the dictionary after the first
  use. Fix and add a test case.
* `ZSTD_DCtx_reset()` always cleared the dictionary. Fix and add a test
  case.
* After calling `ZSTD_resetDStream()` you could no longer load a
  dictionary, since the stage was set to `zdss_loadHeader`. Fix and add
  a test case.

Cleanup:

* Make `ZSTD_initDStream*()` and `ZSTD_resetDStream()` wrap the new
 advanced API, and add test cases.
* Document the equivalent of these functions in the advanced API and
  document the unstable functions as deprecated.

48a6427d22 [libzstd] Fix ZSTD_compress2() for multithreaded compression 
`ZSTD_compress2()` wouldn't wait for multithreaded compression to
finish. We didn't find this because ZSTDMT will block when it can
compress all in one go, but it can't do that if it doesn't have enough
output space, or if `ZSTD_c_rsyncable` is enabled.

Since we will already sometimes block when using `ZSTD_e_end`, I've
changed `ZSTD_e_end` and `ZSTD_e_flush` to guarantee maximum forward
progress. This simplifies the API, and helps users avoid the easy bug
that was made in `ZSTD_compress2()`

* Found by the libfuzzer fuzzers.
* Added a test case that catches the problem.
* I will make the fuzzers sometimes allocate less than
  `ZSTD_compressBound()` output space.

d7d89513d6 Stabilize advance API 
This commit moves the candidate advanced API to the stable section.
It makes some minor whitespace changes, but it doesn't change any
of the wording of the documentation.

I'll put up a separate PR that tweaks some of the documentation
once this lands, so that it is easier to review.

NOTE: Even though these functions are now in stable, they aren't
stable until the next release (in under 1 month). It is possible
that they change until then.
