Fix the following build failure with -Dsingle_threaded=true on embedded
toolchains without pthread:

Since Meson 0.51, there are special build options for "native:true"
builds, prefixed with "build.". This change breaks cross builds
because `janet-boot/src_core_asm.c` is no longer built with `-std=c99`:

Don't search for cross compilerUnless needed.
This should help prevent issues building Meson on debian. Also
fix issue using the wrong set of flags to build the native janet
interpreter vs. the cross compiled janet interpreter.
This means we no longer need to guess paths after install.
Custom directory layouts can now be better supported at install
time without need for environment variables.

Simpler and more flexible interface, and also lets
us use epoll more easily on linux, which is the most important
plantform to optimize for network performance.
This way we can support fewer build configurations. Also, remove
all undefined behavior due to use of memcpy with NULL pointers. GCC
was exploiting this to remove NULL checks in some builds.
In some cases, one might want to disable what is currently
SipHash for speed / better security mechansims. For example, using
red black trees for caches rather than hash tables.
Because we use an amalgated build, feature
test macros should be set in a single file that
is included before any other headers, and is placed
at the top of the amalgamated build.
This allows easy builds of the full interpreter with no
build system.
1. Get janet.c, janet.h, janetconf.h, and shell.c in a directory. Edit
janetconf.h as desired.
2. gcc shell.c janet.c -lm -ldl -O2 -o janet (on GNU-Linux for example)
3. ./janet -h (Yay!)
This makes it easier to get the CLI functionality when
embedding Janet, although the main reason is the init script
is now pre-compiled to bytecode when generating the boot image.
Instead, combine cook into jpm so we can manipulate
JANET_PATH without messing with jpm. path was moved to
and external repository, https://github.com/janet-lang/path.git
Mostly changes to cook and jpm. Also some
code for file associations in the windows installer, and
adding the :linux value from os/which (instead of just :posix).
