This is how it should've been and brings it more in line with
std::string_view. There should be no functional change here.
This is mostly mechanical from a custom clang-tidy check, with a lot of
manual fixups. It uncovers a lot of minor inefficiencies.
This doesn't actually modify StringRef yet, I'll do that in a follow-up.
Now that we've moved to C++14, we no longer need the llvm::make_unique
implementation from STLExtras.h. This patch is a mechanical replacement
of (hopefully) all the llvm::make_unique instances across the monorepo.

to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

This breaks the OpenFlags enumeration into two separate
enumerations: OpenFlags and CreationDisposition. The first
controls the behavior of the API depending on whether or not
the target file already exists, and is not a flags-based
enum. The second controls more flags-like values.
This yields a more easy to understand API, while also allowing
flags to be passed to the openForRead api, where most of the
values didn't make sense before. This also makes the apis more
testable as it becomes easy to enumerate all the configurations
which make sense, so I've added many new tests to exercise all
the different values.

Most of the handling is pretty straightforward; fetch the default
memory flags for the specific resource type before parsing the flags
and apply them on top of that, except that some flags imply others
and some flags clear more than one flag.
For icons and cursors, the flags set get passed on to all individual
single icon/cursor resources, while only some flags affect the icon/cursor
group resource.
For stringtables, the behaviour is pretty simple; the first stringtable
resource of a bundle sets the flags for the whole bundle.
The output of these tests match rc.exe byte for byte.
The actual use of these memory flags is deprecated and they have no
effect since Win16, but some resource script files may still happen
to have them in place.

Previously these fields were only read from this header for cursors,
while Planes was hardcoded to 1 for icons (with a comment that it was
unknown why this was needed) and BitCount was left at the value
read originally in the RESDIRENTRY.
This fixes the single byte that was differing for the icon/cursor test
compared to rc.exe.
This is based on research/testing by Nico Weber.

When preprocessing resource scripts (which can easily be done outside
of llvm-rc), included headers can leave behind C declarations (despite
preprocessing with -DRC_INVOKED), that can't be parsed by a resource
compiler.
This is handled in all of rc.exe, by parsing the preprocessor output
line markers and ignoring content from files named *.h and *.c,
documented at [1].
In addition to this filtering, strip out any other preprocessor directive
that is left behind (like pragmas) which also can't be handled by the
tokenizer.
The added test uses both standard #line markers (supported by rc.exe) and
GNU style extended line markers, thus this test doesn't pass with rc.exe,
but passes with GNU windres. (Windres on the other hand doesn't filter
out files named *.c, only *.h.)

-1 is commonly used as ID for controls that one don't want to
refer to later. For DIALOG resources, the IDs are 16 bit numbers,
and -1 gets interpreted as UINT32_MAX earlier, which then later is
too large to write into a uint16_t.

Normally when writing something that requires padding, we first
measure the length of the written payload data, then write
padding if necessary.
For a recursive structure like versioninfo, this means that the
padding is excluded from the size of the inner element, but
included in the size of the enclosing block.
Rc.exe excludes the final padding (but not the padding of earlier
children) from all levels of the hierarchy.
To achieve this, don't pad after each block or value, but only
before starting the next one. We still pad after completing the
toplevel versioninfo resource, so this won't affect other resource
types.

Previously we would only look in the current directory for a

This allows the escape sequences (\a, \n, \r, \t, \\, \x[0-9a-f]*,
\[0-7]*, "") to appear in .rc scripts. These are parsed and output in
the same way as it's done in original MS implementation.
The way these sequences are processed depends on the type of the
resource it resides in, and on whether the user declared the string to
be "wide" or "narrow".
I tried to maintain the maximum compatibility with the original tool
(and fail in some erroneous situations that are accepted by .rc).
However, there are some (extremely rare) cases where Microsoft tool
outputs nonsense. I found it infeasible to detect such casses.

This is part 6 of llvm-rc serialization.
This adds ability to output cursors and icons as resources.
Unfortunately, we can't just copy .cur or .ico files to output - as each
file might contain multiple images, each of them needs to be unpacked
and stored as a separate resource. This forces us to parse cursor and
icon contents. (Fortunately, these formats are pretty similar and can be
processed by mostly common code).
As test files are binary, here is a short explanation of .cur and .ico
files stored:
cursor.cur, cursor-8.cur, cursor-32.cur are sample correct cursor files,
differing in their bit depth.
icon-old.ico, icon-new.ico are sample correct icon files;
icon-png.ico is a sample correct icon file in PNG format (instead of
usual BMP);
cursor-eof.cur is an incorrect cursor file - this is cursor.cur with
some of its final bytes removed.
cursor-bad-offset.cur is an incorrect cursor file - image header states
that image data begins at offset 0xFFFFFFFF.
Sample correct cursors and icons were created by Nico Weber.
