libsysprof-analyze: add support for external debug dirs
...
The ELF loader can use a set of external debug dirs which will be used to
resolve .gnu_debuglink symbols.

libsysprof-analyze: process SysprofElfLoader:debug-dirs
...
This needs to process the debug-dirs as if they're within the mount
namespace of the target process.
We still need to do external-debug-dirs, but that will be slightly
difference as it does not need further translation.

libsysprof-analyze: add overlay mountinfo parsing test
...
This just ensures that we can parse the contents of the superblock options
that we get for "overlay" mounts via toolbox/podman. These still need to
be handled from SysprofMountNamespace when translating though.
Additionally, this stuff seems very brittle for parsing, unless it is
getting escaped somewhere I'm missing currently.

libsysprof-analyze: remove duplicates in address layout
...
And use a GPtrArray for them instead of gsequence, as it makes it nicer
to remove duplicates using a bitset.

libsysprof-analyze: sanitize address ranges
...
That way we are clamped to what the mapping actually provides. This only
seems to get messed up with glibc, but not clear why and it's barely off
so perhaps it has some special mapping tricks it does.
I still notice some non-reproducible runs, but that appears to be related
to duplicate address mapping entries for [stack] which we need to clear
up by removing the duplicate (short) entry.

libsysprof-analyze: check cached ELF for build-id/file-inode
...
Just because it's cached doesn't mean we should just trust it. It could
have gotten added to the cache previously even though we didn't match.

this fixes some of the cases for captures we already generate.

libsysprof-analyze: treat overlay as SysprofMount

libsysprof-analyze: add SysprofDocumentCtrset
...
This represents the SysprofCaptureCtrset and allows fetching the raw values
for a given counter. These are raw because they may not be endian swapped
and that is the responsibility of the consumer.
SysprofDocument will use these eventually to store the values for a given
counter and the time of the value shift.

libsysprof-analyze: add SysprofDocumentJitmap
...
This adds a specific frame type for the Jitmap frames in the capture files.
You can iterate them without having to bswap as well, which is why this
does not use the SysprofCaptureJitmapIter (which does require bswap'd
frames).
