This replaces using file_util to open and unlink temporary files (/dev/shm on Linux, $TMPDIR or /tmp otherwise) with the POSIX shm_open API, or ashmem on Android (which doesn't implement shm_open). glibc maps shm_open/shm_unlink to open and unlink in /dev/shm (as does musl libc), so the Linux situation is mostly unchanged except we aren't duplicating code from system libraries. Other OSes may (and some do) use more efficient implementations than temporary files. FreeBSD's SHM_ANON extension is used if available. Sadly, it's not standard; it would make this patch much simpler if it were. This patch changes the shm file names; they now start with "org.mozilla" instead of "org.chromium" because the original Chromium code is mostly gone at this point. When running as a Snap package, the required filename prefix is added; other container/sandbox environments using AppArmor to restrict the allowed filenames may need to be adjusted. The shm names now include the creating process's pid, to allow using sandboxing to prevent interfering with shm belonging to other applications or other processes within the same browser instance.
