History
Justine Tunney 7b26b42769 Pay off more technical debt 
This makes breaking changes to add underscores to many non-standard
function names provided by the c library. MODE=tiny is now tinier and
we now use smaller locks that are better for tiny apps in this mode.
Some headers have been renamed to be in the same folder as the build
package, so it'll be easier to know which build dependency is needed.
Certain old misguided interfaces have been removed. Intel intrinsics
headers are now listed in libc/isystem (but not in the amalgamation)
to help further improve open source compatibility. Header complexity
has also been reduced. Lastly, more shell scripts are now available.

Compared to 6f7d0cb1c3, some tiny corrections were made in libc/intrin/g_fds.c and libc/zipos/open.c including double semi colons and incorrect indentation for existing vista changes that were manually pulled from this commit previously.

DESCRIPTION

  plinko is a simple lisp interpreter that takes advantage of advanced
  operating system features irrespective of their practicality such as
  using the nsa instruction popcount for mark sweep garbage collection
  overcommit memory, segment registers, and other dirty hacks that the
  popular interpreters cannot do; this lets plinko gain a considerable
  performance edge while retaining an event greater edge in simplicity

  We hope you find these sources informative, educational, and possibly
  useful too. Lisp source code, written in its dialect is included too
  under //tool/plinko/lib and unit tests which clarify their usage can
  be found in //test/tool/plinko.
