Subject: [PATCH] find-debuginfo: Add -v,--verbose for per file messages
Only print messages what big steps we are at without --verbose.
For a reader of rpmbuild's log, it's rather unclear what find-debuginfo
is doing. It used to be too verbose, "extracting debug info from FILE"
for every file, and while this can be suppressed now, we still end up
with something semi-mysterious like this:
...
extracting debug info from /builddir/build/BUILDROOT/xyz
gdb-add-index: No index was created for /builddir/build/BUILDROOT/xyz
gdb-add-index: [Was there no debuginfo? Was there already an index?]

...
The reader is left confused. "What these cpio errors are about?
Why those sources are not found?" (Well, because not every source
name extracted by 'debugedit -l' has to exist, but this requires
considerable digging aroung to understand).
We can give a few messages explaining what general steps we go through:
Extracting debug info from N files
DWARF-compressing N files
Creating .debug symlinks for symlinks to ELF files
Copying sources found by 'debugedit -l'
This is also useful to get a feeling which steps are time consuming.
Kernel builds often need to investigate this aspect. To help a bit more,
add "find-debuginfo: starting" and "find-debuginfo: done" messages too.
This patch adds these messages.
The -q options suppress these messages too.
It also adds a --verbose flag to print per file messages.
Those per file messages are now suppressed by default and
only the general step messages are show. Unless -q is given,
which suppresses all non-error output.
