meson: get version up front
Run the scraper command to establish the project version immediately,
rather than wait for the build to be configured. This simplifies the
code and ensures that project introspection works correctly.

[contrib][linux] Disable ASM in the kernel
Disable ASM in the kernel for now. It requires a few changes & setup to
get working. Instead of doing it in a zstd version update, I'd prefer to
package that change as a single patch, and propose it separately from
the version update. This makes the version update easier, and reduces
some risk.

[lazy] Use switch instead of indirect function calls. (#3295)
Use a switch statement to select the search function instead of an
indirect function call. This results in a sizable performance win.
This PR is a modification of the approach taken in PR #2828.
When I measured performance for that commit, it was neutral.
However, I now see a performance regression on gcc, but still
neutral on clang. I'm measuring on the same platform, but with
newer compilers. The new approach beats both the current dev
branch and the baseline before PR #2828 was merged.
This PR is necessary for Issue #3275, to update zstd in the kernel.
Without this PR there is a large regression in greedy - btlazy2
compression speed. With this PR it is about neutral.
Add a `--spdx` option to the freestanding script to prefix
files with a line like (for `.c` files):
// SPDX-License-Identifier: GPL-2.0+ OR BSD-3-Clause
or (for `.h` and `.S` files):
/* SPDX-License-Identifier: GPL-2.0+ OR BSD-3-Clause */
Given the style of the line to be used depends on the extension,
a simple `sed` insert command would not work.
It also skips the file if an existing SPDX line is there,
as well as raising an error if an unexpected SPDX line appears
anywhere else in the file, as well as for unexpected
file extensions.
I double-checked that all currently generated files appear
to be license as expected with:
grep -LRF 'This source code is licensed under both the BSD-style license (found in the' linux/lib/zstd
grep -LRF 'LICENSE file in the root directory of this source tree) and the GPLv2 (found' linux/lib/zstd
but somebody knowledgable on the licensing of the project should
double-check this is the intended case.

Make ZSTD_getDictID_fromDDict() Read DictID from DDict
Currently this function actually reads the dict ID from the dictionary's
header, via `ZSTD_getDictID_fromDict()`. But during decompression the decomp-
ressor actually compares the dict ID in the frame header with the dict ID in
the DDict. Now of course the dict ID in the dictionary contents and the dict
ID in the DDict struct *should* be the same. But in cases of memory corrupt-
ion, where they can drift out of sync, it's misleading for this function to
read it again from the dict buffer rather then return the dict ID that will
actually be used.
Also doing it this way avoids rechecking the magic and so on and so it is a
tiny bit more efficient.

fixed zstd-pgo target for GCC
Since your Makefile uses obj/$(HASH_DIR) for object files, this code does not work correctly for GCC. Because profiles are saved in one directory, and are expected in another when reading.
`$(RM) zstd *.o` - this line doesn't delete object files.
Clang stores profiles in the current directory, so the problem doesn't appear when compiling with Clang.

ci: test pkg-config file
As mentioned in
https://github.com/facebook/zstd/pull/3252#issuecomment-1251733791 ,
this patch adds a CI job that builds and installs libzstd on the job
runner, and then compiles a sample binary linking against the installed
library; the needed build flags are passed by invoking pkg-config.

compress:check more bytes to reduce ZSTD_count call
Comparing 4B instead of comparing 1B in ZSTD_noDict
mode, thus it can avoid cases like match in match[ml]
but mismatch in match[ml-3]..match[ml-1]. So the call
count of ZSTD_count can be reduced.

When creating a new `Makefile` target to build,
it's also necessary to update the `clean` target,
which purpose is to remove built targets when they are present.
This process is simple, but it's also easy to forget :
since there is a large distance between the position in the `Makefile` where the new built target is added,
and the place where the list of files to `clean` is defined.
Moreover, the list of files becomes pretty long over time,
hence it's difficult to visually ensure that all built targets are present there,
or that no old target (no longer produced) is no longer in the list
This PR tries to improve this process by adding a CLEAN variable.
Now, when a new built target is added to the `Makefile`,
it should preceded by :
```
CLEAN += newTarget
newTarget:
<TAB> ...recipe...
```
This new requirement is somewhat similar to `.PHONY: newTarget` for non-built targets.
This new method offers the advantage of locality :
there is no separate place in the file to maintain a list of files to clean.
This makes maintenance of `make clean` easier.

build(cmake): improve pkg-config generation
With this patch the pkg-config generation when using the CMake build
system is improved in the following ways:
- Libs.private is now filled when needed
- The JoinPaths module is now used to join paths, leading to simpler
code
- The .pc file is always generated, regardless of the platform, as it
can also be consumed on Windows
Here's how the .pc file is affected by these changes, in comparison to
the one generated with the official Makefiles:
projects / thirdparty / zstd.git / log
