João Távora aa181cd352 Rewrite flex completion with Gotoh algorithm 
The greedy regexp matching, broken scoring and broken highlight were
sources of frequent complaints about the 'flex' matching style.  This
commit fixes that.

Inspired by the 'hotfuzz' style (available at
https://github.com/axelf4/hotfuzz) it uses a modified version of Gotoh's
1982 dynamic programming algorithm. It is strictly more correct than the
"old" flex.  For example, when matching the pattern 'goto' to no longer
will 'eglot-format' be sorted before some hypothetical much better
'goobarbaz-goto'.  And of course the highlighting is also correctly
placed on the 'goto', not scattered across the candidate.

Regarding performance, it is faster than the naive 'flex', primarily
because of the Elisp rewrite in minibuffer.el.  The matching and costing
algorithm matters but is not the bottleneck.

The Elisp parts of the style were almost completely decoupled from the
pcm/substring styles in lisp/minibuffer.el.  Only
'completion-flex-try-completion' uses some of pcm's code for pattern
augmentation.

README 

This directory contains source code for the parts of Emacs that are
written in Emacs Lisp.  *.el files are Emacs Lisp source, and the
corresponding *.elc files are byte-compiled versions.  Byte-compiled
files are architecture-independent.

The term subdirectory contains Lisp files that customize Emacs for
certain terminal types.  When Emacs starts, it checks the TERM
environment variable to get the terminal type and loads
'term/${TERM}.el' if it exists.

The other subdirectories hold Lisp packages grouped by their general
purpose.
