This patch introduces new module parameter, dev, which takes a string
representing the device that the external synth is connected to, e.g.
ttyS0, ttyUSB0 etc. This is then used to communicate with the synth.
That way, speakup can support more than ttyS*. As of this patch, it
only supports ttyS*, ttyUSB* and selected synths for lp*. dev parameter
is only available for tty-migrated synths.
Users will either use dev or ser as both serve same purpose. This patch
maintains backward compatility by allowing ser to be specified. When
both are specified, whichever is non-default, i.e. not ttyS0, is used.
If both are non-default then dev is used.

This changes the above five synths to TTY-based comms. They were chosen as a
first pass because their serial comms are straightforward, i.e. they don't use
serial input and don't do internal port knocking.

serialio.c
This moves spk_synth_immediate and spk_serial_synth_probe functions into
serialio.c. These functions do outgoing serial comms. The move is a step
towards collecting all serial comms in serialio.c. This also renames
spk_synth_immediate to spk_serial_synth_immediate.
Code inside those functions has not been changed. Along the way, this patch
also fixes a couple of spots which were calling spk_synth_immediate directly,
so that the calls now happen via the spk_syth struct.

This patch adds spk_io_ops struct which contain those methods whose job is to
communicate with synth device. Currently, all comms with external synth
device use raw serial i/o. The idea is to group all methods which do the
actual communication with external device into this new struct. Then migrating
a serial-based synth over to an alternative to raw serial i/o will mean
swapping serial spk_io_ops instance with the io_ops instance of the new
method, making the migration simpler.
At the moment, this struct only contains one method, synth_out but more will
be added in future when migrating synths which require input functionality.
Also at the moment, synth_out method has one implementation which uses
serial i/o. Plan is to add an alternative.

Macro module_spk_synth can be used for speakup drivers
whose init and exit paths does only module registrations.
So, here remove some boilerplate code by using
module_spk_synth.

In line with practice for module parameters, we're adding a build-time
check that sysfs files aren't world-writable.

It uses the unnecessary S_IFREG bit which broke when my
stricter-checking-for-mode patch went in.
Since we're fixing it anyway, the extra level of indirection is
confusing for readers (ROOT_W == rw-r--r-- for example).
Also, many of these are other-writable. Is that really intended?
