commit 4a90cb11140a6bb3712228861a32e4035013ad85

libdwfl: Find and handle compressed vmlinuz image.
Both the dwfl_linux_kernel_find_elf callback and the
dwfl_linux_kernel_report_offline reporting function only handled
vmlinix images possibly compressed with .gz, .bz2 or .xz extension.
They did not find or handle the much more common vmlinuz compressed
images.
It is not completely clear why we didn't up to now. Support for
compressed ELF files was added in 2009 and the code was updated to
to try to find the .gz, .bz2 or .xz extension variants in 2011.
But not the vmlinuz named variant.

debuginfod: Fix implicit conversion from 'CURLcode' to 'CURLMcode'
GCC10 warns when converting the value of one enum type into another:
debuginfod-client.c:530:24: error: implicit conversion from ‘CURLcode’
to ‘CURLMcode’ [-Werror=enum-conversion]
530 | curl_res = curl_easy_getinfo(target_handle,
| ^
libcurl has different error code enums. The "easy" interfaces return
a CURLcode error. The "multi" interface functions return a CURLMcode.

commit d8bad02afc7b7f30402b4e0e458df874a6d600da

debuginfod: Check the DEBUGINFOD_URLS environment variable early in client.
If the debuginfod-client isn't configured we should do as little
as possible. Simply return early with ENOSYS if no servers are
configured. This means we won't check
This does change the behavior of the debuginfod_find calls slightly.
Previously we would setup and check the cache if the given build-id
was valid. Which might have provided a result if an earlier client
had run with the same cache and valid server URLs which knew about
that particular build-id. Now we don't return any cached results
unless at least one server is configured.
This prevents selinux errors when the library is used in a confined
setup.

debuginfod: usability tweaks, incl. $DEBUGINFOD_PROGRESS client support
This facility allows a default progress-printing function to be
installed if the given environment variable is set. Some larger usage
experience (systemtap fetching kernels) indicates the default timeout
is too short, so forked it into a connection timeout (default short)
and a transfer timeout (default unlimited).

debuginfod: pass a distro-summary User-Agent request header
It may be useful for a debuginfod server operator to know what kinds
of clients make webapi requests. This is mainly as a
telemetry/diagnostic (though the data cannot be really trusted). It
may also be useful to automate downloading of distro packages to a
debuginfod server in the case of an unknown hex buildid. doc/testing
not affected as these are diagnostics.

debuginfod: Use DEBUGINFOD_TIMEOUT as seconds to get at least 100K.
Use just one timeout using CURLOPT_LOW_SPEED_TIME (default 90 seconds)
and CURLOPT_LOW_SPEED_LIMIT (100K).

An earlier variant of the default progress function could write to any
file. Which is still in the documentation. But the actual implementation
just uses stderr. Fix the documentation to match.

libasm.h: Don't include libebl.h. Define an opaque Ebl handle.
Using libasm isn't really usable without a way to create an Ebl handle.
But we don't support libebl.h (and libebl itself). Just define the
Ebl handle as an opaque struct. Code that uses it needs to figure out
how to instantiate one itself (they cannot in any supportable way...)
