chore: use for(;;) instead of while
In the codebase we have used empty for loop for infinite conditions, so
to bring consistency replaced other occurrences of while in the codebase

win: fix uv_spawn() ENOMEM on empty env
Commit ba780231 ("unix,win: handle zero-sized allocations uniformly")
makes `uv__malloc()` return NULL when `size == 0`.

That's exactly the size that is passed to it when uv_spawn() tries to
spawn a process with an empty environment so handle that edge case.

win,pipe: fix IPC pipe deadlock
This fixes a bug where IPC pipe communication would deadlock when both
ends of the pipe are written to simultaneously, and the kernel pipe
buffer has already been filled up by earlier writes.

The root cause of the deadlock is that, while writes to an IPC pipe are
generally asynchronous, the IPC frame header is written synchronously.
So when both ends of the pipe are sending a frame header at the same
time, neither will read data off the pipe, causing both header writes
to block indefinitely.

Additionally, this patch somewhat reduces the spaghetti level in
win/pipe.c.

c272f1f1bc memory: add uv_replace_allocator
With uv_replace_allocator, it's possible to override the default
memory allocator's malloc and free calls with functions of the user's
choosing. This allows libuv to interoperate with projects requiring a
custom memory allocator.

Internally, all calls to malloc and free have been replaced with
uv__malloc and uv__free, respectively. The uv__malloc and uv__free
functions call malloc and free unless they have been overridden by a
previous call to uv_replace_allocator.

As part of this change, the special aligned memory allocations
performed in src/win/fs-event.c have been replaced with standard
allocations. The 4-byte alignment being requested in this file was
unnecessary, since standard allocators already guarantee at least an
8-byte alignment.

c7e4b31444 windows: read the PATH env var of the child
The unix and windows process implementations diverge in their behavior
when dealing with subprocesses that are spawned with a relative path.
With unix the *child's* PATH environment variable is read, whereas
with windows the *parent's* environment variable is read.

This commit brings the two implementation in line with respect to
their behavior of reading PATH by having both read the *child's* PATH
environment variable. This involves looking into the user-provided
environment on windows and extracting the PATH variable specifically
so it can be inspected later on.

The PATH-parsing code for windows erroneously contained an infinite

6f62d62c90 windows: always initialize uv_process_t
The unix implementation of uv_spawn always starts out with a
uv__handle_init, but the windows implementation sometimes bails out
early before calling uv__handle_init. This means that uv_close on a
failed uv_spawn will always succeed on unix but sometimes fail on
windows.

This commit lifts the initialization of the uv_process_t above all of
the error checking to ensure that uv_close will always work when
uv_spawn returns an error.

f764bff699 unix: return exec errors from uv_spawn, not async
If spawning a process fails due to an exec() failure (but it succeeded
in forking), then this should be considered a spawn failure instead of
an asynchronous termination of the process. This allows to check for
common exec() failure conditions such as a bad path quickly instead of
having to rely on keeping track of the async callback.

Additionally, the meaning of the two fields returned in the callback are
now exactly what they advertise to be. The process exit argument is not
one of two values depending on what happened to the child.

Fixes #978.

3ee4d3f183 unix, windows: return error codes directly
This commit changes the libuv API to return error codes directly rather
than storing them in a loop-global field.

A code snippet like this one:

    if (uv_foo(loop) < 0) {
      uv_err_t err = uv_last_error(loop);
      fprintf(stderr, "%s\n", uv_strerror(err));
    }

Should be rewritten like this:

    int err = uv_foo(loop);
    if (err < 0)
      fprintf(stderr, "%s\n", uv_strerror(err));

The rationale for this change is that it should make creating bindings
for other languages a lot easier: dealing with struct return values is
painful with most FFIs and often downright buggy.
