80b211e314 Add raw memory visualization tool to redbean
This change introduces a `-W /dev/pts/1` flag to redbean. What it does
is use the mincore() system call to create a dual-screen terminal
display that lets you troubleshoot the virtual address space. This is
useful since page faults are an important thing to consider when using a
forking web server. Now we have a colorful visualization of which pages
are going to fault and which ones are resident in memory.

The memory monitor, if enabled, spawns as a thread that just outputs
ANSI codes to the second terminal in a loop. In order to make this
happen using the new clone() polyfill, stdio is now thread safe.

This change also introduces some new demo pages to redbean. It also
polishes the demos we already have, to look a bit nicer and more
presentable for the upcoming release, with better explanations too.

cfc3a953ae Use 64-bit years
This change makes strftime() go faster and makes it possible to format
timestamps through the big bang to most of the stelliferous era. India
has also been added as a timezone to most binaries. Since we were able
to change the struct tm abi, this makes cosmopolitan libc superior, to
just about everything else, when it comes to standing the test of time
