Make more use of the built in GC code for abstracts to
be sure things are more correct. Issue before was streams could
be freed before IOCP events arrived.
Instead of setting a flag, each interrupt increments an atomic
counter. When the interrupt is finally handled, either by scheduling
code to run on the event loop or executing some out of band code, the
user must now decrement the interrupt counter with
janet_interpreter_interrupt_handled. While this counter is non-zero, the
event loop will not enter the interpreter. This changes the API a bit but
makes it possible and easy to handle signals without race conditions
or scheduler hacks, as the runtime can ensure that high priority code is
run before re-entering possibly blocking interpreter code again.
Also included is a new function janet_schedule_soon, which prepends to
the task queue instead of appending, allowing interrupt handler to skip
ahead of all other scheduled fibers.
Lastly, also update meson default options to include the
interpreter_interrupt code and raise a runtime error if os/sigaction
is used with interpreter interrupt but that build option is not enabled.
Threaded channels _can_ be marshalled, just not for communication
between threads. This is a special case since the same abstract type
is used for both threaded and non-threaded channels.

commit 677b8a6f32

Added ARM32 test
When suspended in `ev/give` or `ev/take`, closing the channel should
cause the result of `ev/give` or `ev/take` to be `nil`.
When suspended in `ev/select`, closing the channel should cause the
result of `ev/select` to be `[:close ch]`.
The results were flipped before.
By take and releasing locks twice per channel in the case where nothing
is reading, there was an opportunity for ev/select to hang in the
multithreaded case. Also silence valgrind/helgrind errors.
The sandboxing API is meant to make janet a bit more attractive
for certain application embedding use cases. The sandboxing API
puts limits on what system resources the interpreter can access.
Adds extra information to default information from supervisor
channels. For threaded channels as supervisors, we don't get
the source fiber so identifying the source of messages was not
possible. This change allows better multithreading with supervisors.
Should make janet a bit easier to use. Also changes the
header to not expose the size of native mutexes and rwlocks, except
with janet_os_mutex_size and janet_os_rwlock_size.
FFI may be best implemented as an external library
(libffi has incompatible license to Janet) or as code
that takes void * and wraps then into Janet C functions
given a function signature. Either way, we need to some way
to load symbols from arbitrary dynamic libraries.
This is more intuitive and avoids the possibilty of strange code
to resume or cancel a fiber after it was scheduled but before it was
entered for the first time.
handles returned by CreateFileA and FILE_FLAG_OVERLAPPED
support reading from arbitrary offsets.
The offset is passed to ReadFile in through the OVERLAPPED structure.
Since state->overlapped is zeroed ev_machine_read
ReadFile would always read from the start of the file and never finish
This commit changes ev_machine_read to update the offset to
the number of bytes read before calling ReadFile.
