The inclusions were removed with the following very crude script and the
resulting breakage was fixed up by hand. The manual fixups did either
revert the changes done by the script, replace a generic header with a more
specific one or replace a header with a forward declaration.

Large clipboard data (in nsTransferable) in content processes is no
longer stored in a temporary file, but kept in memory.

Right now CreateDataFromPrimitive doesn't use the aDataLen parameter, and after this change the out
value should be the same as the value passed in, as long as we are dealing with strings.

This combines some of your ideas from D8074, in which I think is quite a big improvement to the overall code.
The code for nsTransferable::GetTransferData, especially nsIFlavorDataProvider is a bit wonky, because I tried to preserve the current behavior.

Running clang-format makes this code at least a bit more pleasant to look at.

DataStruct cannot safely be copied if its mCacheFD member is set.
Currently there is no code for this case, but to avoid problems later,
mark the copy and assignment constructors private and delete them.
A move-constructor was added to compensate for the deleted copy
constructor. nsTransferable::AddDataFlavor uses this new constructor
instead of the previous implicit default copy constructor.

Ensure that only DataStruct::mData + mDataLen, XOR
DataStruct::mCacheFD is used.
(Previously it was possible that all of these members were populated,
which is a waste of memory.)
The effect of this change is visible when SetTransferData is called
multiple times with the same flavor, but with one below the threshold
for storing in-memory, and the other above (=store in a file).

The cache file is never directly exposed to consumers of DataStruct,
so it does not make sense to keep the clipboardcache file around
forever.
The only change in this commit is to switch from using a filename to
using a file descriptor. In the destructor, the FD is explicitly closed
(which releases the file data). nsAnonymousTemporaryFile takes care
of removing the file when the destructor is not called (e.g. crashes).
Previously, the clipboard cache was stored in a file called:
TmpD/clipboardcache-N
As of this commit, the clipboard cache is stored at:
TmpD/mozilla-temp-randomN (macOS and Linux)
TmpD/mozilla-temp-files/mozilla-temp-randomN (Windows)
(see xpcom/io/nsAnonymousTemporaryFile.{h,cpp} for more details)
To verify that these files are really gone:
1. Create a document with 500k+ characters, open it in Firefox.
2. Copy its content - this will trigger the clipboard cache.
3. Look for the open file descriptor of the deleted file:
( macOS and Linux: )
lsof +L1 | grep mozilla-temp
4. Copy anything (under the 500k threshold), or quit/kill Firefox.
5. Repeat step 3 and observe that the number of file descriptors
has decreased.

We shouldn't assume it's safe to write to /tmp unless we know
for sure we are not in a private browsing window. So
use mPrivateData = true as default.

This is straightforward, with only two notable things.
- `#include "nsXPIDLString.h" is replaced with `#include "nsString.h"`
throughout, because all nsXPIDLString.h did was include nsString.h. The
exception is for files which already include nsString.h, in which case the
patch just removes the nsXPIDLString.h inclusion.
- The patch removes the |xpidl_string| gtest, but improves the |voided| test to
cover some of its ground, e.g. testing Adopt(nullptr).

This converts |nsITransferable.flavorsTransferableCanExport| and
|nsITransferable.flavorsTransferableCanImport| to return a |nsIArray|.
|nsIFormatConverter.getInputDataFlavors| and
|nsIFormatConverter.getOutputDataFlavors| are updated as well.
