basic riscv support 
llvm is giving me `error: couldn't allocate output register for
constraint '{a0}'` which is a bug that needs to be fixed upstream.

move some of the installation from cmake to zig build 
This moves the installation of shipped source files from large
CMakeLists.txt lists to zig build recursive directory installation.

On my computer a cmake `make install` takes 2.4 seconds even when it has
to do nothing, and prints a lot of unnecessary lines to stdout that say
"up-to-date: [some file it is installing]".

After this commit, the default output of `make` is down to 1
second, and it does not print any junk to stdout. Further, a `make
install` is no longer required and `make` is sufficient.

This closes #2874.

It also closes #2585. `make` now always invokes `zig build` for
installing files and libuserland.a, and zig's own caching system makes
that go fast.

cap getdents length argument to INT_MAX 
the linux syscall treats this argument as having type int, so passing
extremely long buffer sizes would be misinterpreted by the kernel.
since "short reads" are always acceptable, just cap it down.

patch based on musl commit 3d178a7e2b75066593fbd5705742c5808395d90d

73ee434c8c Use /dev/urandom and sysctl(RANDOM_UUID) on Linux. 
Add fallback paths for when the getrandom(2) system call is not
available.  Try /dev/urandom first and sysctl(RANDOM_UUID) second.

The sysctl issues a warning in the system logs with some kernels but
that seems like an acceptable tradeoff for the fallback of a fallback.

3671582c15 syntax: functions require return type. remove -> 
The purpose of this is:

 * Only one way to do things
 * Changing a function with void return type to return a possible
   error becomes a 1 character change, subtly encouraging
   people to use errors.

See #632

Here are some imperfect sed commands for performing this update:

remove arrow:

```
sed -i 's/\(\bfn\b.*\)-> /\1/g' $(find . -name "*.zig")
```

add void:

```
sed -i 's/\(\bfn\b.*\))\s*{/\1) void {/g' $(find ../ -name "*.zig")
```

Some cleanup may be necessary, but this should do the bulk of the work.
