The [5ec3a584: Generate upcase and downcase tables from Unicode data]
commit broke bootstrap from a truly clean tree (e.g. a fresh clone or
one created with ‘make extraclean’), see
<http://hydra.nixos.org/build/48774928>.

The failure was caused by characters.el trying to read Unicode
property tables which aren’t available so early in the build process.

Wrap the part that requires Unicode property tables in a condition
checking if those are available.  If they aren’t they case and syntax
tables won’t be fully set but later on, the characters.el file will be
evaluated again and this time with Unicode properties available so
final Emacs ends up with the exact same case and syntax tables.

Improve regexp to search html meta tag.

Check that operand is a hash table and hashes to ints.

* lisp/emacs-lisp/bytecomp.el (byte-compile-lapcode): Don't do
  redundant operations while calculating the correct jump addresses
  from TAGs in jump tables.

A compatibility digraph characters, such as Dž, are neither upper- nor
lower-case.  At the moment however, those are reported as upper-case¹
despite the fact that they change when upper-cased.

Stop checking if a character is upper-case before trying to up-case it
so that title-case characters are handled correctly.  This fixes one of
the issues mentioned in bug#24603.

¹ Because they change when converted to lower-case.  Notice an asymmetry
  in that for a character to be considered lower-case it must not be
  upper-case (plus the usual condition of changing when upper-cased).

* src/buffer.h (upcase1): Delete.
(upcase): Change to upcase character unconditionally just like downcase
does it.  This is what upcase1 was.

* src/casefiddle.c (casify_object, casify_region): Use upcase instead
of upcase1 and don’t check !uppercasep(x) before calling upcase.

* src/keyboard.c (read_key_sequence): Don’t check if uppercase(x), just
downcase(x) and see if it changed.

* test/src/casefiddle-tests.el (casefiddle-tests--characters,
casefiddle-tests-casing): Update test cases which are now passing.

Use Unicode data to generate case tables instead of mostly repeating
them in lisp code.  Do that in a way which maps ‘Dz’ (and similar)
digraph to ‘dz’ when down- and ‘DZ’ when upcasing.

https://debbugs.gnu.org/cgi/bugreport.cgi?msg=89;bug=24603 lists all
changes to syntax table and case tables introduced by this commit.

* lisp/international/characters.el: Remove case-pairs defined with
explicit Lisp code and instead use Unicode character properties.

* test/src/casefiddle-tests.el (casefiddle-tests--characters,
casefiddle-tests-casing): Update test cases which are now working
as they should.

Fixes cases marked FIXME upcoming in followup commits.

* test/src/casefiddle-tests.el (casefiddle-tests-char-properties,
casefiddle-tests-case-table, casefiddle-tests-casing-character,
casefiddle-tests-casing, casefiddle-tests-casing-byte8,
casefiddle-tests-casing-byte8-with-changes): New tests.
(casefiddle-tests--test-casing): New helper function for runnig
some of the tests.
