* if (result == ULLONG_MAX) is always false, likely a typo as
result is unsigned long, and the comment says ULONG_MAX.
* use off_t instead of size_t for file size where it can mismatch
st_size's type in stat.h

This only eliminates errors reported by `make lint`. It shouldn't cause any
functional changes.
This change does remove several functions that are unused. It also removes the
`desc_arr` variable which is both unused and out of date with reality.

This removes some pointless parentheses but the primary focus is removing
redundancies like unnecessary "else" clauses.

Reduces lint errors from 121 to 52 (-57%). Line count from 1916 to 1671 (-13%).
Another step in resolving issue #2902.

Remove the "make iwyu" build target. Move the functionality into the
recently introduced lint.fish script. Fix a lot, but not all, of the
include-what-you-use errors. Specifically, it fixes all of the IWYU errors
on my OS X server but only removes some of them on my Ubuntu 14.04 server.
Fixes #2957

Refine the linting behavior.
Fix several of the, mostly trivial, lint errors.

This is a quick and dirty conversion of the atypical, and undocumented,
logging done by env_universal_common.cpp to the usual `debug()` pattern. I
didn't want to drop the messages because they could be useful when
debugging future issues. So I simply converted them to the lowest debug
level using the normal debug() function.
Fixes #2887

The u_int typedef fails to compile on all platforms (e.g. Windows). It
is part of the code imported from tmux.
Update it to the SUS-standard uid_t.
Closes #2821.

Address the feedback from the prior commit:
- Change the sense of return value testing to match more common
comparison idiom
- Test result of fchmod as well as fchown
- Change sense of return value testing around wrename as well
- Include errno where possible in error message

The function fchown is annotated with warn_unused_result. As
formerly used in the code, it would emit a compiler warning
```warning: ignoring return value of ‘fchown’, declared with
attribute warn_unused_result [-Wunused-result]```
This commit notes the return value and emits appropriate error/logging
messages if the call fails, creating more traceable results and
satisfying the compiler.

Previously, when decoding UTF-8, we would first run through the
array to compute the correct size, then allocate a buffer of that size,
then run through the array again to fill the buffer, and then copy it
into a std::wstring. With this fix we can copy it into the string
directly, reducing allocations and only requiring a single pass.

We identify when the universal variable file has changed out from under us by
comparing a bunch of fields from its stat: inode, device, size, high-precision
timestamp, generation. Linux aggressively reuses inodes, and the size may be
the same by coincidence (which is the case in the tests). Also, Linux
officially has nanosecond precision, but in practice it seems to only uses
millisecond precision for storing mtimes. Thus if there are three or more
updates within a millisecond, every field we check may be the same, and we are
vulnerable to the ABA problem. I believe this explains the occasional test
failures.
The solution is to manually set the nanosecond field of the mtime timestamp to
something unlikely to be duplicated, like a random number, or better yet, the
current time (with nanosecond precision). This is more in the spirit of the
timestamp, and it means we're around a million times less likely to collide.
This seems to fix the tests.

Cygwin FIFOs do not support more than one reader, so avoid them on this
platform. An autoconf feature test would be helpful but is tricky to
write.
Closes #2152.

This change moves source files into a src/ directory,
and puts object files into an obj/ directory. The Makefile
and xcode project are updated accordingly.
Fixes #1866
