build: set OS=="android" for android builds

Work around the build name issues by instead manually adding the build
target for android builds using '-DOS=android'

This additionally resolves problems caused by the OS variable being
rewritten from "android" to "linux" in gyp. This causes errors, as
real-time support (-lrt) and pthread support (-lpthread) is not
available in the android NDK toolchain as libraries.

The functions present in these libraries are included automatically
during the build instead during the android compilation process.
windows: don't use uppercase in include filename

Change <Winsock2.h> to <winsock2.h>. The former breaks
cross-compilation with mingw.
test: open stdout fd in write-only mode

Fixes #771.
windows: uv_spawn shouldn't reject reparse points

This fixes an issue where uv_spawn would not try to run a reparse point,
and continue to scan the PATH instead. Effectively, it was impossible to
spawn a symlinked binary. This commit fixes that.

Also see #748
stream: add an API to make streams do blocking writes

This patch adds the `uv_stream_set_blocking` API which makes all
uv_write calls to that stream blocking. It currently only works for
pipes, on windows.
windows: use WSAGetLastError(), not errno

setsockopt() doesn't touch errno on failure. Use WSAGetLastError()
instead.

setsockopt() doesn't touch errno on failure. Use WSAGetLastError()

This is a back-port of commit 30a8b44 from the master branch.
build: darwin: disable -fstrict-aliasing warnings

gcc 4.2.1 as shipped with Xcode complains incessantly about aliasing
warnings, which, while technically true, disregards the fact that the
aliased types have the same layout in memory. Squelch the warnings.
test: fix signed/unsigned compiler warning
test: add 'start timer from check handle' test

Check that a timer that is started from a check handle gets picked up
correctly, i.e. that it influences the timeout used in the next tick
of the event loop.
build: `all` now builds static and dynamic lib

The `make all` target now builds both libuv.a and libuv.{so,dylib}
rather than just libuv.a.

build: add install target to the makefile

Before this commit, there was no way to install libuv other than
manually copying required files to the path. This commit introduces
an install target which installs the libuv.a, libuv.so and header files
to the install prefix.

    ``
    make
    make install
    ``

The above will use the default prefix `/usr/local`

    ``
    make
    make install PREFIX=/usr
    ``

The above will install to `/usr`
build: switch to autotools

Switch to the build tool everyone loves to hate.  The Makefile has
served us well over the years but it's been acquiring more and more
features that autotools gives us for free, like easy static+shared
library building, sane install targets, and so on.

This commit drops MinGW support.  If there is demand for it, we'll
re-add it.
build: use AM_PROG_AR conditionally

AM_PROG_AR does not exist in automake v0.11 but without it, you can't
build libuv with automake v0.12+ on Darwin.
test: fix fs_fstat test on sunos

The tests are no longer compiled with -D_XOPEN_SOURCE=500 when building
with autotools. Tell the test explicitly that SunOS systems are
expected to have nanosecond fstat(2) granularity.
test: fix fs_chown when running as root

chown(2) to root is expected to fail - unless you're root, of course.
