Add a `#else` line to `toolsrc/src/vcpkg/base/files.cpp`. On Linux
and macOS, there are specific ways to copy from file descriptor to file
descriptor, but on FreeBSD there isn't (as far as I could tell). This
change does a copy using the POSIX standard `read` and `write` calls.
(This change was to `RealFilesystem::rename_or_copy`).
We expect to have people on FreeBSD install CMake themselves, and use
`./bootstrap.sh -useSystemBinaries`, in order to build vcpkg.
Since CMake 3.15.2 exists in the FreeBSD 12 (latest stable) package
manager, it's trivial to install it.

- Add the "VCPKG_DEVELOPMENT_WARNINGS" flag
- setting "WERROR" will also set this flag
- This flag is set by default
- on GCC/clang, this will pass '-Wall -Wextra -Wpedantic -Werror'
- on GCC, this will additionally pass '-Wmissing-declarations'
- on clang, this will additionally pass '-Wmissing-prototypes'
- on MSVC, this will pass '-W4 -WX'
- On Visual Studio 2017 and later, pass '-permissive-'
- Change the source for fallout of these changes
- add `format` subcommand
- formats all C++ source and header files using clang-format
- move `include/vcpkg-test/catch.h` to `include/catch2/catch.hpp`
- pass CONFIGURE_DEPENDS to file(GLOB)

The VS2015 standard library requires, in debug mode, a comparison
operator on `T × U` and `U × T` to also be a comparison operator on
`T × T` and on `U × U`, and so in
vcpkg::Install::install_package::intersection_compare, I've added two
new `operator()` overloads which take those respectively, on VS2015.
Also, `[nodiscard]` was added to somewhere in `vcpkg/base/strings.h`,
which gives a warning in VS2015 -- thus, I added the `vcpkg/pragmas.h`
include, since that fixes the warning.
I was building under /W3, because CMake hadn't been set up to build
under /W4 -- therefore, I didn't see some warnings.
We also decided to remove the niebloids and instead break ADL by using
`= delete`, since otherwise we get warnings when we define a local
variable with the same name as a niebloid. I also removed `status` and
`symlink_status` from the `files` header, since it's unnecessary now,
and they're just implementation details of `RealFilesystem`.
I also removed some existing uses of unqualified `status(path)`, since
that no longer compiles. I also added `Filesystem::canonical`, to remove
another use of `fs::stdfs` in a function I was already working in.
There's a bug in `std::experimental::filesystem::status` on
libstdc++ -- it incorrectly sets its `error_code` when a file
doesn't exist, or when a path doesn't exist. In order to get
around this, `error_code` was cleared when the file doesn't exist,
but it was not cleared when the path didn't exist.
Note: in this case, I say "the file doesn't exist" when, if you
look up "a/b/c", "a/b" exists but "c" doesn't. I say "the path
doesn't exist" when, if you look up "a/b/c", either "a" or "a/b"
doesn't exist.
I added benchmarks to measure how fast the parallel remove_all code was
-- it turns out, about 3x slower than stdfs::remove_all. Since this was
the case, I removed all of the parallelism and rewrote it serially, and
ended up about 30% faster than stdfs::remove_all (in addition to
supporting symlinks).
In addition, I did the following three orthogonal changes:
- simplified the work queue, basing it on Billy O'Neal's idea
- Fix warnings on older versions of compilers in tests, by splitting
the pragmas out of pch.h.
- Ran clang-format on some files
In fixing up remove_all, the following changes were made:
- On Windows, regular symlinks and directory symlinks are distinct;
as an example, to remove directory symlinks (and junctions, for that
matter), one must use RemoveDirectory. Only on Windows, I added new
`file_type` and `file_status` types, with `file_type` including a new
`directory_symlink` enumerator, and `file_status` being exactly the
same as the old one except using the new `file_type`. On Unix, I
didn't make that change since they don't make a distinction.
- I added new `symlink_status` and `status` functions which use the
new `file_status` on Windows.
- I made `Filesystem::exists` call `fs::exists(status(p))`, as opposed
to the old version which called `stdfs::exists` directly.
- Added benchmarks to `vcpkg-test/files.cpp`. They test the
performance of `remove_all` on small directories (~20 files), with
symlinks and without, and on large directories (~2000 files), with
symlinks and without.
* better logic expression evaluation
Improve the logic expression evaluation currently used when filtering
dependencies.
Biggest improvements:
+ Allow '|' operator
+ Support nested '()'
+ Allow whitespace
+ Useful error message for malformed expressions
Also changed names of types to RawParagraph when that is what the original author was using.
This PR does the following:
* fix tests -- now, they're always built in the CMake scripts, and they work on VS2015
*add a new flag, BUILD_TESTING, which allows one to turn off testing builds
* Add documentation for running tests
- when an option is not recognized (perhaps because it has trailing whitespace characters), print it out enclosed with single quote to delimit and highlight potenatial not printable characters.
