Pull request description:
Adds replacements for `gsign` and `gverify`.
Personally I'm not a big fan of using the word "sign" as it's been used to refer to both codesigning and GPG signing.

The Qt Resource Compiler (rcc) has a command-line option
`--format-version` which has the default value 2.
The only difference from `--format-version 1` is adding a last modified
timestamp to the output file. That, in turn, forces us to use
`QT_RCC_SOURCE_DATE_OVERRIDE=1` to get deterministic builds.
This change makes rcc output always deterministic by using
`--format-version 1` option that makes usage of the
`QT_RCC_SOURCE_DATE_OVERRIDE` needless. Also it improves interaction
with ccache.

46b025e00d test: add new python linter to check file names and permissions (windsok)
6f6bb3ebc7 test: fix file permissions on various scripts (windsok)
Pull request description:
Adds a new python linter test which tests for correct filenames and file permissions in the repository.
Replaces the existing tests in the `test/lint/lint-filenames.sh` and `test/lint/lint-shebang.sh` linter tests, as well as adding some new and increased testing. This increased coverage is intended to catch issues such as in #21728 and https://github.com/bitcoin/bitcoin/pull/16807/files#r345547050
Summary of tests:
* Checks every file in the repository against an allowed regexp to make sure only lowercase or uppercase alphanumerics (a-zA-Z0-9), underscores (_), hyphens (-), at (@) and dots (.) are used in repository filenames.
* Checks only source files (*.cpp, *.h, *.py, *.sh) against a stricter allowed regexp to make sure only lowercase alphanumerics (a-z0-9), underscores (_), hyphens (-) and dots (.) are used in source code filenames. Additionally there is an exception regexp for directories or files which are excepted from matching this regexp (This should replicate the existing `test/lint/lint-filenames.sh` test)
* Checks all files in the repository match an allowed executable or non-executable file permission octal. Additionally checks that for executable files, the file contains a shebang line.
* Checks that for executable `.py` and `.sh` files, the shebang line used matches an allowable list of shebangs (This should replicate the existing `test/lint/lint-shebang.sh` test)
* Checks every file that contains a shebang line to ensure it has an executable permission
Additionally updates the permissions on various files to comply with the new tests.

We already attest to the relevant dist-archive in inputs.SHA256SUMS,
which is recorded at build-time.
We use a SKIPATTEST.TAG file to indicate output directories which do not
require attestation (much like the CACHEDIR.TAG specification).
Generally, it's better to have build scripts declare properties of
directories instead of introducing name-based special cases in attest
scripts since build scripts have a more detailed context of what is
going on.
At build/codesigning-time, hash build inputs and output the digest to
${OUTDIR}/inputs.SHA256SUMS, which gets included in the final SHA256SUMS
constructed by guix-attest.
Example final SHA256SUMS:

While files are being output to $OUTDIR, it will be under
${DISTSRC}/output, and only when everything is done, will
${DISTSRC}/output be moved to the actual $OUTDIR.
This makes it so that a Ctrl-C in the middle of a build is less likely
to result in a partially-constructed $OUTDIR. In fact, if I understand
correctly, if $OUTDIR and $DISTSRC reside on the same filesystem, the
move (rename) is likely atomic.
Also, since the "working $OUTDIR" is under ${DISTSRC}/output, it will be
cleaned properly by the guix-clean script.
This relatively easy change eliminates all runtime dependencies (except
for the kernel) for dmg, which is the only native build tool that gets
put in our output tarballs.
This allows much more flexibility when constructing the codesigning
environment, and is much more robust.
./windeploy is a "working directory", and therefore belongs inside
distsrc-*. Many people have noticed their Guix builds failing after
hours simply because they did not remove windeploy (but did remove the
distsrc-* directories).
In Guix, there are two flags for controlling parallelism:
Note: When I say "derivation," think "package"
--cores=n
- controls the number of CPU cores to build each derivation. This is
the value passed to `make`'s `--jobs=` flag.
- defaults to 0: as many cores as is available
--max-jobs=n
- controls how many derivations can be built in parallel
- defaults to 1
Therefore, if set --max-jobs=$MAX_JOBS and don't set --cores, Guix could
theoretically spin up $MAX_JOBS * $(nproc) number of threads, and that's
no good.
So we could either default to --cores=1, --max-jobs=$MAX_JOBS
- Pro: --cores=1 means that `make` will be invoked with `-j1`,
avoiding problems with package whose build systems and test
suites break when running multi-threaded.
- Con: There will be times when only 1 or 2 derivations can be built
at a time, because the rest of the dependency graph all depend
on those 1 or 2 derivations. During these times, the machine
will be severely under-utilized.
or --cores=$MAX_JOBS, --max-jobs=1
- Pro: We don't encounter prolonged periods of
severe under-utilization mentioned above.
- Con: Many packages' build systems and test suites break when running
multi-threaded.
or --cores=1, --max-jobs=1 and let the user override with

The new time-machine commit is Guix v1.2.0 with a yet-unupstreamed patch
for NSIS.
A few important changes:
1. Guix switched back from using CPATH to C{,PLUS}_INCLUDE_PATH as the
way to indicate #include search paths.
2. GCC's library is now split into a separate output, whereas before it
was included in the default output. This means that our gcc toolchain
packages need to propagate that output.
3. A few package versions were bumped
Any -O argument will enable optimizations in GNU ld. We can use -O2
here, as this matches our compile flags. Note that this would also
enable additional optimizations if using the lld or gold linkers,
when compared to -O0.
This is no longer needed after 3bef7c22 in the mingw-w64 git repository,
which is first included in mingw-w64 v7.0.0.
As of the previous bump to our Guix time machine, we now use mingw-w64
v7.0.0.
- Add "--no-insert-timestamp" LDFLAG for x86_64-w64-mingw32 builds
"The option --no-insert-timestamp can be used to insert a zero value for
the timestamp, this ensuring that binaries produced from identical
sources will compare identically." - ld(1)
- Set "SetDateSave off" in NSIS script
From https://nsis.sourceforge.io/Docs/Chapter4.html#flags
"This command sets the file date/time saving flag which is used by the
File command to determine whether or not to save the last write date and
time of the file, so that it can be restored on installation. Valid
flags are 'on' and 'off'. 'on' is the default."
- Add commented out NSIS options for reproducibility debugging in NSIS
script
- Make ZIPs deterministic by reseting file modification times to
SOURCE_DATE_EPOCH using touch(1) (Reference:
https://reproducible-builds.org/docs/archives/)
- store_path() previously only worked for cross compilation packages, we
remove this assumption here
- Add CROSS_GCC_LIB variable which points to where gcc libs/headers are
located
- Add gcc libs/headers to our CROSS_*_PATH environment variables
- Check that all directories in CROSS_*_PATH are sane
