Hack around https://sourceware.org/bugzilla/show_bug.cgi?id=12674
by providing a custom implementation for glibc < 2.21 in terms of other
concurrency primitives.
The glibc implementation on these versions is inherently unsafe.
So, while libuv and Node.js support those versions, it seems to make
sense for libuv in its functionality as a platform abstraction library
to provide a working version.

Problem:
The instructions assume you have already installed gyp to
build/gyp.
If you run 'make' without doing so, it asks you to read the README,
which does not actually tell you about installing gyp.

Add a one-liner `git clone` command to the setup instructions.

Fix bug in `uv__pollfds_del()` where only one invalidated fd is purged.
Calls to `uv__platform_invalidate_fd()` will invalidate descriptors
(rather than removing them) when `poll()` is iterating. Under stressful
conditions, this may happen more frequently than `uv__pollfds_del()` is
called. So, when uv__pollfds_del() is called with a value of -1, it
should iterate the entire array to remove all invalidated descriptors.

This commit refactors uv_os_homedir() to to use uv_os_getenv()
to retrieve the USERPROFILE environment variable. This removes
a fair amount of duplicated code, while introducing the following
changes:
1. The function no longer returns UV_EIO when USERPROFILE is
longer than MAX_PATH. This can be reinstated by adding a
check for r == 0 && *size >= MAX_PATH.
2. The USERPROFILE string is now a char*, meaning that it must
be converted from utf8 to utf16 by uv_os_getenv().

- Remove the `active_reqs` queue, which is never used. There are more
efficient per-stream queues that `libuv` uses whenever it needs this
information, so duplicating it and managing it here seems
like unnecessary extra space and work.
- Unix `uv_loop_init` didn't explicitly initialize.
`loop->active_handles` (although it did memset the whole struct
to 0, so it wasn't wrong previously, just inconsistent).
- Consolidate repeated code for `uv__has_active_reqs`.
- Change `uv__loop_alive` to use the helper functions (mirroring the
unix copy of the same function).
- Initialize some more uv_stream_t fields in init, rather than waiting
for the connection callback. This helps surface bugs in libuv or the
caller better, since it ensures libuv doesn't see uninitialized
memory if asked to look at these fields before it thinks the socket
is connected.
- Fixes what appears to be a double-counting of `handle->reqs_pending`,
in the highly-unlikely event that the code wants to emulate IOCP,
but `RegisterWaitForSingleObject` somehow managed to fail.

`UV_READABLE_PIPE` and `UV_WRITABLE_PIPE` flags should be honored on
unices.
Windows is better about already doing this, so this will make the
behavior of these flags more consistent across platforms.
It also is just better to set these flags to reflect the actual
mode of the stream, rather than guessing at it based on typical usage.
