Vlastimil Ovčáčík 00fb486f6a [tests] Add testing of keyboard events in FullscreenRenderer.GetChar()
This contains one test case of each tcell.Key* event type that can be
sent to and subsequently processed in fzf's GetChar(). The test cases
describe status quo, and all of them PASS.

Small function util.ToTty() was added. It is similar to util.IsTty(),
but for stdout (hence the To preposition).

Do not print non-displayable characters
fzf used to print non-displayable characters (ascii code < 32) as '?',
but we will simply ignore those characters with this patch, just like
our terminals do.

\n and \r are exceptions. They will be printed as a space character.

TODO: \H should delete the preceding character, but this is not implemented.

Micro-optimizations
- Make structs smaller
- Introduce Result struct and use it to represent matched items instead of
  reusing Item struct for that purpose
- Avoid unnecessary memory allocation
- Avoid growing slice from the initial capacity
- Code cleanup

[perf] Avoid allocating rune array for ascii string
In the best case (all ascii), this reduces the memory footprint by 60%
and the response time by 15% to 20%. In the worst case (every line has
non-ascii characters), 3 to 4% overhead is observed.

Junegunn Choi 92a75c9563 Use trimmed length when --nth is used with --tiebreak=length
This change improves sort ordering for aligned tabular input.
Given the following input:

    apple   juice   100
    apple   pie     200

fzf --nth=2 will now prefer the one with pie. Before this change fzf
compared "juice   " and "pie     ", both of which have the same length.

Junegunn Choi 2fe1e28220 Improvements in performance and memory usage
I profiled fzf and it turned out that it was spending significant amount
of time repeatedly converting character arrays into Unicode codepoints.
This commit greatly improves search performance after the initial scan
by memoizing the converted results.

This commit also addresses the problem of unbounded memory usage of fzf.
fzf is a short-lived process that usually processes small input, so it
was implemented to cache the intermediate results very aggressively with
no notion of cache expiration/eviction. I still think a proper
implementation of caching scheme is definitely an overkill. Instead this
commit introduces limits to the maximum size (or minimum selectivity) of
the intermediate results that can be cached.
