completion: simplify __git_complete_revlist_file

index-pack: restructure pack processing into three main functions

The second pass in parse_pack_objects() are split into
resolve_deltas(). The final phase, fixing thin pack or just seal the
pack, is now in conclude_pack() function. Main pack processing is now
a sequence of these functions:

 - parse_pack_objects() reads through the input pack
 - resolve_deltas()     makes sure all deltas can be resolved
 - conclude_pack()      seals the output pack
 - write_idx_file()     writes companion index file
 - final()              moves the pack/index to proper place

index-pack: support multithreaded delta resolving

This puts delta resolving on each base on a separate thread, one base
cache per thread. Per-thread data is grouped in struct thread_local.
When running with nr_threads == 1, no pthreads calls are made. The
system essentially runs in non-thread mode.

An experiment on a Xeon 24 core machine with git.git shows that
performance does not increase proportional to the number of cores. So
by default, we use maximum 3 cores. Some numbers with --threads from 1
to 16:

index-pack: disable threading if NO_PREAD is defined

NO_PREAD simulates pread() as a sequence of seek, read, seek in
compat/pread.c. The simulation is not thread-safe because another
thread could move the file offset away in the middle of pread
operation. Do not allow threading in that case.

l10n: de.po: translate "remote" as "extern"

The word "remote" was translated as "entfernt"

because "anders" in German means "other" and
"entfernt" has two different meanings and could
result in confusion to the users.
We've changed the translation to "extern".
