Makefile.build: easier compilation with timings info

 On a reasonable platform equipped with a /usr/bin/time, a simple
 "make TIMED=1" should provide you with timings of the .v compilations.

 If you don't have /usr/bin/time, or prefer a different output format,
 you can still do a "make TIMECMD='...'".

 For storing the timings in a spreadsheet, simply do:
 "make TIMED=1 2> timings.csv"
 and then import this csv in your favorite office program,
 with whitespace as separator.

Improving error message when abtraction over goal (abstract_list_all
used when applying schemes - induction, rewrite, ...) is well-typed
but not of the right type.

Suggest to use clean rather than archclean before recompiling.
For instance, generated files depend on whether configuration is done
with dynlink or not and they should be cleaned.

Repaired configure damaged in r15748 for those bash users which have
CDPATH variable set. Indeed, command cd is verbose when CDPATH is set,
what would introduce garbage in the generated file config/coq_config.ml.

More accurate timings for "Time foo"

 The elapsed time in seconds was computed via a difference of Unix.time(),
 but these Unix.time() aren't precise enough (just a number of seconds),
 and a difference is hence even less precise.  We now use Unix.gettimeofday,
 and round the time difference to the millisecond.

Repair the configure after Hugo's last "repair" ;-)

 Ok, I wasn't aware of the funny behavior of cd in presence of $CDPATH.
 But the last "repair" was worse, trying to write into non-existing file
 theories/config/coq_config.ml

 Things should be better now:

 * no more Coq_config.theories_dirs at all, since it was completely unused :-)

 * concerning Coq_config.plugins_dirs, we list them without any "cd" into plugins,
   hence keeping the "plugins/" part in their paths, and adapt accordingly
   the only use (!) of plugins_dirs, in coq_makefile

 Please run ./configure again after upgrading to this commit

Fix a confusion between types of locations in an untyped part of the parser
after the migration of compat.ml4

 This was leading to huge positions written to .glob files, making
 coqdoc loop forever.

Clean-up of proof_type.ml : no more Nested nor abstract_tactic_box

 Nested was never constructed, while the notion of abstract_tactic_box
 is obsolete (cf. Refiner.abstract_tactic).

Clean-up : removal of Proof_type.tactic_expr

 This instance of gen_tactic_expr was used only to decorate
 tactics via Refiner.abstract_tactics and alii, but these
 expressions are now ignored by the new proof-engine (no "info"...).
