I'm not 100% sure whether the behavior of readlink() with size=0 is
well-defined on Solaris; it can return either 0 or fail with EINVAL.
POSIX is not explicit about the mandated behavior.
This commit adds a little caution and makes it skip the readlink()
call when size=1 and simply writes the terminating zero byte.

uv_exepath() should write as much as possible to the output buffer.
In the case of size=1, skip the call to readlink() because it will
fail with EINVAL; just write the terminating zero byte.

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.

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.

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`.

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.

The test used to call uv_cwd() twice, in this fashion:
char buf[PATH_MAX];
size_t size = sizeof buf;
uv_cwd(buf, &size);
uv_cwd(buf, &size);
The `size` variable is supposed to contain the buffer size (including
terminating null) on input, and it is also used as an out parameter for
returning the actual length of the working directory (not including the
terminating null). This makes the second uv_cwd() call fail with
UV_ENOBUFS.
