Enable passing additional variables for synthetic uevents that
are generated by writing /sys/.../uevent file.

- Recognized extended format is ACTION [UUID [KEY=VALUE ...].

+ The ACTION is compulsory - it is the name of the uevent
+ action (``add``, ``change``, ``remove``). There is no change

You need to pass UUID first before any KEY=VALUE pairs.
- The UUID must be in "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
+ The UUID must be in ``xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx``
format where 'x' is a hex digit. The UUID is considered to be
a transaction identifier so it's possible to use the same UUID
value for one or more synthetic uevents in which case we
logically group these uevents together for any userspace
listeners. The UUID value appears in uevent as
- "SYNTH_UUID=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" environment
+ ``SYNTH_UUID=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx`` environment
variable.

If UUID is not passed in, the generated synthetic uevent gains
- "SYNTH_UUID=0" environment variable automatically.
+ ``SYNTH_UUID=0`` environment variable automatically.

The KEY=VALUE pairs can contain alphanumeric characters only.

It's possible to define zero or more pairs - each pair is then
delimited by a space character ' '. Each pair appears in
- synthetic uevent as "SYNTH_ARG_KEY=VALUE". That means the KEY
- name gains "SYNTH_ARG_" prefix to avoid possible collisions
+ synthetic uevent as ``SYNTH_ARG_KEY=VALUE``. That means the KEY
