This can practically easily be a product of combining strings with
macros in resource files.
This fixes https://github.com/mstorsjo/llvm-mingw/issues/140.
As string literals within llvm-rc are handled as StringRefs, each
referencing an uninterpreted slice of the input file, with actual
interpretation of the input string (codepage handling, unescaping etc)
done only right before writing them out to disk, it's hard to
concatenate them other than just bundling them up in a vector,
without rearchitecting a large part of llvm-rc.
This matches how the same already is supported in VersionInfoValue,
with a std::vector<IntOrString> Values.
MS rc.exe only supports concatenated string literals in version info
values (already supported), string tables (implemented in this patch)
and user data resources (easily implemented in a separate patch, but
hasn't been requested by any end user yet), while GNU windres supports
string immediates split into multiple strings anywhere (e.g. like
(100 ICON "myicon" ".ico"). Not sure if concatenation in other
statements actually is used in the wild though, in resource files
normally built by GNU windres.

This seems to be used in some resource files, e.g.
f3217573d7/include/wx/msw/wx.rc (L28).
MSVC rc.exe and GNU windres both allow any value here, and silently
just truncate to uint16_t range. This just explicitly allows the
-1 value and errors out on others - the same was done for control
IDs in dialogs in c1a67857ba.

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.

This adds the missing input files used for this test, except for
the separate input files for specific error cases; matching
test input files were provided by Nico Weber.
The extra copying of files into the %t directory doesn't seem to
be necessary since that directory only ever is used for output here,
not for inputs.

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.
