win: remap ERROR_NOACCESS and ERROR_BUFFER_OVERFLOW (#4567)

It seemed incorrect to map a segfault to EACCES, since posix would typically
map this to EFAULT. The ERROR_BUFFER_OVERFLOW is literally "the filename is too
long", and is not typically an invalid parameter in posix.

Test originally added in #1060 to test the API, not the value.

win,error: remap ERROR_NO_DATA to EAGAIN (#4471)

This was incorrectly mapped originally, which makes for confusing error
messages about an EPIPE if a program happens to (unwisely) set PIPE_WAIT
on the handle. It is unclear to me if libuv should try to handle this in
some meaningful way, and very unclear what that way would look like, but
at least expose this to the caller with the correct errno translation.

win,errors: remap ERROR_ACCESS_DENIED to UV_EACCES (#3193)

If we try to use uv_fs_rmdir on a read-only directory on Windows, it
internally calls _wrmdir, which sets _doserrno to ERROR_ACCESS_DENIED
and errno to EACCES. However, ERROR_ACCESS_DENIED is mapped to
UV_EPERM, so I believe it should be remapped to UV_EACCES.

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.

win: Map ERROR_INVALID_FUNCTION to EISDIR

This error is raised when calling read() or write() on a directory.

A bit of googling turns up some cases where this error can be raised
that are not properly mapped to EISDIR, but are also cases that libuv
doesn't really care about, like the Password Manager API,
GetFirmwareEnvironmentVariable, or CreateTapePartition.

If libuv ever needs to handle these cases, then I suppose that the
ERROR_INVALID_FUNCTION->EISDIR mapping could be done directly in the
fs read() and write() functions, but doing so at this point seems
premature, as it makes the error code mapping a bit more messy.
