darwin: fix uv_exepath(smallbuf) UV_EPERM error

Passing a buffer that was too small to hold the result made it fail
with UV_EPERM because the -1 status code from _NSGetExecutablePath()
was returned unmodified to the caller.

This commit rewrites uv_exepath() to:

1. Not allocate heap memory, and

2. Not clobber the result buffer on error, and

3. Handle _NSGetExecutablePath()'s and realpath()'s idiosyncracies, and

4. Store as much of the path in the output buffer as possible, don't
fail with an error. Makes it behave the same as other platforms.
The result is always zero-terminated.

linux: fix support for preadv/pwritev-less kernels

The fix from commit 269ff0be is wrong in that it sniffs system headers
to determine if preadv() and pwrite() are supported.

It breaks the fs_write_multiple_bufs test on one of my ARM systems;
its glibc has preadv() and pwritev() wrappers but its kernel has no
support for the corresponding system calls.

Simply try the system call and fall back to a normal read or write
loop if not supported. Move the no_preadv and no_pwritev variables
around to squelch two -Wpedantic warnings about mixing declarations
with code.

Revert "unix: only set SO_REUSEADDR when bind() fails"

This reverts commit a9e95a33bc723dc42daea2fcde6dde1d4cc5efad.

This seems to cause regressions in the test suite when IPv6 is disabled.

As optimizations go, it's a very minor one so let's not spend too much
effort trying to track down the cause of the regressions but revert the
change before it makes its way into a release.

test: fix spawn test with autotools build

Fix spawn_reads_child_path when executed as `test/run-tests` or
`make check`:

1. `make check` builds a dynamic libuv.so or libuv.dyld by default.

2. spawn_reads_child_path spawns a new instance of the test runner
by consulting uv_exepath() and executing the result.

3. `test/run-tests` is normally a shell script that sets up
DYLD_LIBRARY_PATH or LD_LIBRARY_PATH before executing the
real test runner in `test/.libs`.

4. uv_exepath() (corectly) returns the path of the binary in
`test/.libs`. The binary is linked against libuv.so but that
library is not on any of the default linker paths; and if it is,
it's almost certainly the wrong version.

5. Ergo, carry over the value of the (DY)LD_LIBRARY_PATH environment
variable into the environment of the child process so that the
dynamic linker knows where to find the library.

Alternatively, we could link the test runner statically against libuv.a
but that breaks `make check` when configured with `--disable-static`.

linux: fix epoll_pwait() sigmask size calculation

Revisit the fix from commit b705b53. The problem with using sigset_t
and _NSIG is that the size of sigset_t and the value of _NSIG depend
on what headers libuv picks up first, <signal.h> or <asm/signal.h>.
With the former, sizeof(sigset_t) = 128; with the latter, it's 8.

Simply sidestep the issue by calculating the signal mask as a 64 bits
integer, without using sigset_t or _NSIG.

This is a partial cherry-pick of commit 751ac48 from the v1.x branch.
