João Távora a0b5ff9bb7 Rewrite flex completion scoring 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.

It was inspired by the 'hotfuzz' style available at
https://github.com/axelf4/hotfuzz which is a modified version of Gotoh's
1982 dynamic programming algorithm (see: GOTOH, Osamu. An improved
algorithm for matching biological sequences. Journal of molecular
biology, 1982, 162.3: 705-708.).  That style is slightly more
sophisticated than 'flex' (has special rules for matching things at word
boundaries, a C module with multithreading support).  It's almost (but
not entirely) void of hacks so it'd make a good candidate to replace
'flex' entirely, but no progress has been made in getting it into
Emacs's core in over 2 years, so I thought I'd try my hand at it.

The new 'flex' implementation also uses Gotoh algorithm (apparently
a common choice for these kinds of task) and happens mostly in a new C
function.  It is strictly more correct than the "old" flex.  For
example, when matching the pattern 'goto' to, say, 'eglot--goto' and
'eglot--bol', no longer is the latter returned first, which was a
substantial annoyance.  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', but that's
mainly because this commit also includes changes to the Elisp code which
make faster regexp's for the filtering step.  It is slower than
'hotfuzz' when that style's C-module extension is leveraged.  'hotfuzz'
does the filtering and sorting steps together in C code and has
multithreaded workers there.  The matching and scoring algorithm itself
is not the bottleneck.

The flex style was completely decoupled from the pcm/substring styles in
lisp/minibuffer.el.  Test code were refactored and more tests were
added.

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.
