cdrom_id udev helper does not parse all MMC profiles. Following change
fixes this issue and parse all 34 profiles from all MMC standard versions.
Also it replaces magic constants by macros provided by linux/cdrom.h and
fixes cd_profiles_old_mmc() to issue READ_DISC_INFO command in two steps,
like it is doing kernel and also mkudffs.
When you have a CD automunt solution that talks directly to the kernel
independently of udev it races with cdrom_id for exclusive access to the
device failing unpredictably.
The whole is_mounted function in cdrom_id is broken: there is no saying
what happens between calling is_mounted and opening the device.
Hence assume that the device can be mounted asynchronously at any time,
do not use exclusive access, and do away with is_mouted.

For some reason they were missed previously. All those files seem to
have proper SDPX tags.
This function is internal to systemd code, so external users of libudev
will not see those log messages. I think this is better. If we want to
allow that, the function could be put in libudev and exported.
v2: check that the string is more than one char before stripping quotes
There are more than enough calls doing string manipulations to deserve
its own files, hence do something about it.
This patch also sorts the #include blocks of all files that needed to be
updated, according to the sorting suggestions from CODING_STYLE. Since
pretty much every file needs our string manipulation functions this
effectively means that most files have sorted #include blocks now.
Also touches a few unrelated include files.
also removes this warning:
