Use C99 array initializer syntax for consistency with other array
initializers around it and to eliminate a sparse warning:

There is a spelling mistake in the module parameter description
for say_word_ctl and an extra space. Fix the spelling mistake and
remove the extraneous space.

This patch includes an enhancement requested frequently on the mailing
list.[1][2] It adds a variable, cur_phonetic in the spk_vars, which can
be set as a module parameter, as well as in /sys/speakup/cur_phonetic.
This patch also documents cur_phonetic as a sysfs attribute in
sysfs-driver-speakup.
When cur_phonetic=1, it causes speakup to speak letters phonetically if
paused on the character while arrowing through a word.
When a user does not set cur_phonetic to any value, the default value
for it would be 0.

This is an enhancement which allows setting default variables for
speakup module at the boot rather than setting the sys variables after
the boot.

This patch fixes a segfault by adding a null check on synth in
speakup_con_update(). The segfault can be reproduced as follows:
- Login into a text console
- Load speakup and speakup_soft modules
- Remove speakup_soft
- Switch to a graphics console
This is caused by lack of a null check on `synth` in
speakup_con_update().
Here's the sequence that causes the segfault:
- When we remove the speakup_soft, synth_release() sets the synth
to null.
- After that, when we change the virtual console to graphics
console, vt_notifier_call() is fired, which then calls
speakup_con_update().
- Inside speakup_con_update() there's no null check on synth,
so it calls synth_printf().
- Inside synth_printf(), synth_buffer_add() and synth_start(),
both access synth, when it is null and causing a segfault.
Therefore adding a null check on synth solves the issue.

- int use_unicode -> bool: it's used as bool at some places already, so
make it explicit.
- int glyph -> u16: every caller passes a u16 in. So make it explicit
too. And remove a negative check from inverse_translate() as it never
could be negative.

The existing code was assuming that bright color names can be forged by just
prepending the "bright" word to the color name. But some langages may rather
append it, or require completely different names ("grey" is actually already an
example).

The cursor tracking modes enum, the edge enum, and the read_all commands
enum should be used as such in the source code, to make it more readable
and make gcc catch missing values in switches.
Also, some values of enums are coupled with others, we at least need to
document these.

speakup_cut() calls speakup_clear_selection() which calls console_lock.
Problem is: speakup_cut() is called from a keyboard interrupt
context. This would hang if speakup_cut is pressed while the console
lock is unfortunately already held.
We can however as well just defer calling clear_selection() until the
already-deferred set_selection_kernel() call.
This was spotted by the lock hardener:
Possible unsafe locking scenario:\x0a
