Optimize lisp/icomplete.el when default completion available
Often, when using icomplete with icomplete-show-matches-on-no-input
and commands like C-h f, icomplete-exhibit will take a long time (like
several seconds) to show all the completions.
However, if there is a non-nil default value, like when the C-h f is
performed exactly on a function name, the minibuffer prompt will
reflect that immediately. If the user immediately presses RE
(icomplete-force-complete-and-exit) we take that to mean "use the
default" and avoid the long wait.

Improve scoring algorithm for flex-style completions
The previous algorithm had two problems: it considered non-matches in
the beginning and end of the string as matching "holes" and failed to
penalize larger holes, making flex-score-match-tightness only
effective in some corner cases.
The new formula, which is described in code and in pseudo-code in the
comments, fixes these problems.
As a result, by default, C-h f flex now correctly bubbles up
"company-search-flex-regexp" to the top, in front of "file-exists-p".
With a flex-score-match-tightness smaller than 1.0, the situation is
reversed.

Allow completion styles to adjust completion metadata
This commit re-does the now-reverted commit with the same title. That
version relied on generic functions, which cannot be used yet in files
such as lisp/minibuffer.el. This version uses a symbol property
completion--adjust-metadata instead.
The new facility allows completion styles to have a say in metadata

generally produce many matches, including some potentially "obscure"
ones. The default sorting strategy would often bubble the latter to
the top of the list.
The sorting function for 'flex' considers pre-computed matching scores
and is thus much better than the default for this particular style.

uses them to pre-sort the result, so that they are still relevant for
resolving ties.
