Refactor all fuzzers to use shared fuzz_helpers.h
Complete the refactoring of all 25 fuzzers:
- Remove duplicate Buffer struct definitions from 15 format fuzzers
- Remove duplicate DataConsumer class from 7 API fuzzers
- Update consume_bytes() calls to match new signature
- All fuzzers now use shared helpers from fuzz_helpers.h
The test runner already lists available tests if it fails to parse the
command line, but add a -l option to explicitly do this without also
printing an error message and a summary of options.
tree_reopen() and tree_dup() return NULL only of they
are unable to allocate memory. Otherwise libarchive enters
ARCHIVE_FATAL if trying to walk an enterable but unreadable
directory.
__archive_ensure_cloexec_flag() operates only on fd >= 0
so there is no need to skip it
Uses the sed-like way (and Java-like, and .Net-like, and Javascript-like…) to fix this issue of advancing the string to be processed by one if the match is zero-length.
Fixes libarchive/libarchive#2725 and solves libarchive/libarchive#2438.
Skip over LZ4/zstd skippable frames when detecting data format
Since LZ4 and zstd share the same format for skippable frames, we need
to skip over these frames when trying to detect the format of compressed
data. Let's read up to something like 64kb of data when performing this
scanning.
Note that the LZ4 specification advises against starting with a skippable
frame, but doesn't forbid it:
> For the purpose of facilitating identification, it is discouraged to
> start a flow of concatenated frames with a skippable frame. If there
> is a need to start such a flow with some user data encapsulated into
> a skippable frame, it's recommended to start with a zero-byte LZ4
> frame followed by a skippable frame. This will make it easier for
> file type identifiers.
Test that we can read lz4 data with leading skippable frames
This is expected to fail until a followup commit, because lz4 and zstd
skippable frames are the same format and we don't skip over those when
performing format detection (yet).
Whenever we need to create a temporary file while writing to disk on a
POSIX system, try to create it in the same directory as the final file
instead of the current working directory. The target directory can
reasonably be expected to be writable (and if it isn't, creating the
file will fail anyway), but the current working directory may not be.
While here, consistently use __archive_mkstemp(), and increase the
template from six to eight random characters.
Raise the maximum size of Mac metadata from 4 MiB to 10 MiB, as that is
the value used by Apple themselves in the version of libarchive included
in Darwin.
Provide preprocessor macros for two recurring magic numbers in the zip
support code: the length of the local file header (30 bytes) and the
maximum allowable size for Mac metadata (4 MiB).
In archive_util.c, we have a private function named get_tempdir() which
is used by __archive_mktemp() to get the temporary directory if the
caller did not pass one.
In archive_read_disk_entry_from_file.c, we use the same logic with a
slight twist (don't trust the environment if setugid) to create a
temporary file for metadata.
Merge the two by renaming get_tempdir() to __archive_get_tempdir() and
unstaticizing it (with a prototype in archive_private.h).

Add a clang module map for libarchive
When compiling libarchive using clang in module mode a special
module.modulemap file describes the structure of the header files
so that they can be imported modularly. Having this file makes
it easier for modular uses of the library out of the box so that
clients don't need to write their own, potentially making errors
in doing so.
Add a module.modulemap in the public header file location so that
clang and related tools can find it easily.
