mfra atom contains two leaf atoms, 'tfra' and 'mfro'. The first one
provides file offsets of the chunks in a isml file.

mfra atom support will not help Smooth Streaming support in VLC (at
least for the client part), but can be useful for other
purposes, e.g. to enable VLC to play a "raw" isml file.

it's confusing enough to cause typos (sum-bluray instead of sum-libbluray)
and break make fetch

And fix unzip behaviour

And drop libxml dependency

This reverts commit b590a13f.

Should close #5571

If we don't build pkg-config (because a previous installation exists
somewhere else), autoconf won't find PKG_* m4 macros and fail to
run on packages using them (if they don't ship the macros either)

This saves a whole lot of float conversion and simplifies the code.

Only 1 second interval has ever been used.

One last full rebuild for this!

The implementation was slow/inefficient. This is really silly for
_performance_ counters. And contrary to the other statistics, nothing
actually reads them, except for debug logs.

If you really want debug-only performance timers, use this:

    mtime_t start, end;

    start = mdate();
    compute_decimals_of_Pi(100);
    end = mdate();
    msg_Dbg(obj, "spent %"PRIu64" us computing", end - start);

So that the user notices it when it doesn't work

Atoms mvex, mehd, trex and sdtp are found at least in PIFF (isml) files.
This a first step towards Smooth Streaming support in VLC.
