Import termbox library from https://github.com/nsf/termbox
Upstream version is no longer maintained.
Discarded python module and "waf" build goop.
Trimmed the README to the essentials and added
a reference to the upstream project.
Renamed some files for clarity.

+## README
+
+This is a fork of https://github.com/nsf/termbox
+as of commit a04f34c11494a1dbfb6286fc95470dea4086c520
+"Add a note: project is no longer maintained"
+
+This README has been trimmed down to just the introduction and changelog
+(below) which remain unchanged from the upstream version:
+
+## Termbox
+
+Termbox is a library that provides minimalistic API which allows the
+programmer to write text-based user interfaces.
+
+It is based on a very simple abstraction. The main idea is viewing terminals as
+a table of fixed-size cells and input being a stream of structured
+messages. Would be fair to say that the model is inspired by windows console
+API. The abstraction itself is not perfect and it may create problems in certain
+areas. The most sensitive ones are copy & pasting and wide characters (mostly
+Chinese, Japanese, Korean (CJK) characters). When it comes to copy & pasting,
+the notion of cells is not really compatible with the idea of text. And CJK
+runes often require more than one cell to display them nicely. Despite the
+mentioned flaws, using such a simple model brings benefits in a form of
+simplicity. And KISS principle is important.
+
+At this point one should realize, that CLI (command-line interfaces) aren't
+really a thing termbox is aimed at. But rather pseudo-graphical user interfaces.
+
+### Getting started
+
+Termbox's interface only consists of 12 functions::
+
+```
+tb_init() // initialization
+tb_shutdown() // shutdown
+
+tb_width() // width of the terminal screen
+tb_height() // height of the terminal screen
+
+tb_clear() // clear buffer
+tb_present() // sync internal buffer with terminal
+
+tb_put_cell()
+tb_change_cell()
+tb_blit() // drawing functions
+
+tb_select_input_mode() // change input mode
+tb_peek_event() // peek a keyboard event
+tb_poll_event() // wait for a keyboard event
+```
+
+See src/termbox.h header file for full detail.
+
+### Changes
+
+v1.1.2:
+
+- Properly include changelog into the tagged version commit. I.e. I messed up
+ by tagging v1.1.1 and describing it in changelog after tagged commit. This
+ commit marked as v1.1.2 includes changelog for both v1.1.1 and v1.1.2. There
+ are no code changes in this minor release.
+
+v1.1.1:
+
+- Ncurses 6.1 compatibility fix. See https://github.com/nsf/termbox-go/issues/185.
+
+v1.1.0:
+
+- API: tb_width() and tb_height() are guaranteed to be negative if the termbox
+ wasn't initialized.
+- API: Output mode switching is now possible, adds 256-color and grayscale color
+ modes.
+- API: Better tb_blit() function. Thanks, Gunnar Zötl <gz@tset.de>.
+- API: New tb_cell_buffer() function for direct back buffer access.
+- API: Add new init function variants which allow using arbitrary file
+ descriptor as a terminal.
+- Improvements in input handling code.
+- Calling tb_shutdown() twice is detected and results in abort() to discourage
+ doing so.
+- Mouse event handling is ported from termbox-go.
+- Paint demo port from termbox-go to demonstrate mouse handling capabilities.
+- Bug fixes in code and documentation.
+
+v1.0.0:
+
+- Remove the Go directory. People generally know about termbox-go and where
+ to look for it.
+- Remove old terminfo-related python scripts and backport the new one from
+ termbox-go.
+- Remove cmake/make-based build scripts, use waf.
+- Add a simple terminfo database parser. Now termbox prefers using the
+ terminfo database if it can be found. Otherwise it still has a fallback
+ built-in database for most popular terminals.
+- Some internal code cleanups and refactorings. The most important change is
+ that termbox doesn't leak meaningless exported symbols like 'keys' and
+ 'funcs' now. Only the ones that have 'tb_' as a prefix are being exported.
+- API: Remove unsigned ints, use plain ints instead.
+- API: Rename UTF-8 functions 'utf8_*' -> 'tb_utf8_*'.
+- API: TB_DEFAULT equals 0 now, it means you can use attributes alones
+ assuming the default color.
+- API: Add TB_REVERSE.
+- API: Add TB_INPUT_CURRENT.
+- Move python module to its own directory and update it due to changes in the
+ termbox library.
