libarchive: Fix use of ssize_t in archive_entry.h
This type is not available on Windows compilers so for clients including
this header we need to use `la_ssize_t` instead as we do in `archive.h`.

libarchive: Define __LA_DEPRECATED consistently
Upstream libarchive now defines this macro in two places with the same
logic in both. However, CMake's bundled copy disables this macro, so
we need to update the new location of its definition to be consistent.

+ * Utility to match up hardlinks.
+ *
+ * The 'struct archive_entry_linkresolver' is a cache of archive entries
+ * for files with multiple links. Here's how to use it:
+ * 1. Create a lookup object with archive_entry_linkresolver_new()
+ * 2. Tell it the archive format you're using.
+ * 3. Hand each archive_entry to archive_entry_linkify().
+ * That function will return 0, 1, or 2 entries that should
+ * be written.
+ * 4. Call archive_entry_linkify(resolver, NULL) until
+ * no more entries are returned.
+ * 5. Call archive_entry_linkresolver_free(resolver) to free resources.
+ *
+ * The entries returned have their hardlink and size fields updated
+ * appropriately. If an entry is passed in that does not refer to
+ * a file with multiple links, it is returned unchanged. The intention
+ * is that you should be able to simply filter all entries through
+ * this machine.
+ *
+ * To make things more efficient, be sure that each entry has a valid
+ * nlinks value. The hardlink cache uses this to track when all links
+ * have been found. If the nlinks value is zero, it will keep every
+ * name in the cache indefinitely, which can use a lot of memory.
+ *
+ * Note that archive_entry_size() is reset to zero if the file
+ * body should not be written to the archive. Pay attention!
+ */
+struct archive_entry_linkresolver;
+
+/*
+ * There are three different strategies for marking hardlinks.
+ * The descriptions below name them after the best-known
+ * formats that rely on each strategy:
+ *
+ * "Old cpio" is the simplest, it always returns any entry unmodified.
+ * As far as I know, only cpio formats use this. Old cpio archives
+ * store every link with the full body; the onus is on the dearchiver
+ * to detect and properly link the files as they are restored.
+ * "tar" is also pretty simple; it caches a copy the first time it sees
+ * any link. Subsequent appearances are modified to be hardlink
+ * references to the first one without any body. Used by all tar
+ * formats, although the newest tar formats permit the "old cpio" strategy
+ * as well. This strategy is very simple for the dearchiver,
+ * and reasonably straightforward for the archiver.
+ * "new cpio" is trickier. It stores the body only with the last
+ * occurrence. The complication is that we might not
+ * see every link to a particular file in a single session, so
+ * there's no easy way to know when we've seen the last occurrence.
+ * The solution here is to queue one link until we see the next.
+ * At the end of the session, you can enumerate any remaining
+ * entries by calling archive_entry_linkify(NULL) and store those
+ * bodies. If you have a file with three links l1, l2, and l3,
+ * you'll get the following behavior if you see all three links:
+ * linkify(l1) => NULL (the resolver stores l1 internally)
+ * linkify(l2) => l1 (resolver stores l2, you write l1)
+ * linkify(l3) => l2, l3 (all links seen, you can write both).
+ * If you only see l1 and l2, you'll get this behavior:
+ * linkify(l1) => NULL
+ * linkify(l2) => l1
+ * linkify(NULL) => l2 (at end, you retrieve remaining links)
+ * As the name suggests, this strategy is used by newer cpio variants.
+ * It's noticeably more complex for the archiver, slightly more complex
+ * for the dearchiver than the tar strategy, but makes it straightforward
+ * to restore a file using any link by simply continuing to scan until
+ * you see a link that is stored with a body. In contrast, the tar
+ * strategy requires you to rescan the archive from the beginning to
+ * correctly extract an arbitrary link.

+ * An overview of ISO 9660 format:

+ * Each disk is laid out as follows:
+ * * 32k reserved for private use
+ * * Volume descriptor table. Each volume descriptor
+ * is 2k and specifies basic format information.
+ * The "Primary Volume Descriptor" (PVD) is defined by the
+ * standard and should always be present; other volume
+ * descriptors include various vendor-specific extensions.
+ * * Files and directories. Each file/dir is specified by
+ * an "extent" (starting sector and length in bytes).
+ * Dirs are just files with directory records packed one
+ * after another. The PVD contains a single dir entry
+ * specifying the location of the root directory. Everything
+ * else follows from there.
+ *
+ * This module works by first reading the volume descriptors, then
+ * building a list of directory entries, sorted by starting
+ * sector. At each step, I look for the earliest dir entry that
+ * hasn't yet been read, seek forward to that location and read
+ * that entry. If it's a dir, I slurp in the new dir entries and
+ * add them to the heap; if it's a regular file, I return the
+ * corresponding archive_entry and wait for the client to request
+ * the file body. This strategy allows us to read most compliant
+ * CDs with a single pass through the data, as required by libarchive.

+ * null bytes, pads size with spaces and other numeric fields with zeroes
+ * = plexus-archiver prior to 2.6.3 (before switching to commons-compress)
+ * may have uid and gid fields filled with spaces without any octal digits
