* add std.event.RwLock and std.event.RwLocked
* std.debug.warn does its printing locked
* add std.Mutex, however it's currently implemented as a spinlock
* rename std.event.Group.cancelAll to std.event.Group.deinit and change
the docs and assumptions.
* add std.HashMap.clone
* add std.atomic.QueueMpsc.isEmpty
* make std.debug.global_allocator thread-safe
* std.event.Loop: now you have to choose between
- initSingleThreaded
- initMultiThreaded
* std.event.Loop multiplexes coroutines onto kernel threads
* Remove std.event.Loop.stop. Instead the event loop run() function
returns once there are no pending coroutines.
* fix crash in ir.cpp for calling methods under some conditions
* small progress self-hosted compiler, analyzing top level declarations
* Introduce std.event.Lock for synchronizing coroutines
* introduce std.event.Locked(T) for data that only 1 coroutine should
modify at once.
* make the self hosted compiler use multi threaded event loop
* make std.heap.DirectAllocator thread-safe
See #174
TODO:
* call sched_getaffinity instead of hard coding thread pool size 4
* support for Windows and MacOS
* #1194
* #1197
This is akin to channels in Go, except:
* implemented in userland
* they are lock-free and thread-safe
* they integrate with the userland event loop
The self hosted compiler is changed to use a channel for events,
and made to stay alive, watching files and performing builds when
things change, however the main.zig file exits after 1 build.
Note that nothing is actually built yet, it just parses the input
and then declares that the build succeeded.
Next items to do:
* add windows and macos support for std.event.Loop
* improve the event loop stop() operation
* make the event loop multiplex coroutines onto kernel threads
* watch source file for updates, and provide AST diffs
(at least list the top level declaration changes)
* top level declaration analysis
See #770

zig-fmt-pointer-reform-2 branch.
This will convert all & into *. Due to the syntax
ambiguity (which is why we are making this change),
even address-of & will turn into *, so you'll have
to manually fix thes instances. You will be guaranteed
to get compile errors for them - expected 'type', found 'foo'
