`strncpy` is deprecated for use on NUL-terminated destination strings [1].
Let's refactor this function to just use synth_write().

This makes all those 'char's an explicit 'u8'. This is part of the
continuing unification of chars and flags to be consistent u8.
This approaches tty_port_default_receive_buf().
Note that we do not change signedness as we compile with
-funsigned-char.

Count passed to tty_ldisc_ops::receive_buf*(), ::lookahead_buf(), and
returned from ::receive_buf2() is expected to be size_t. So set it to
size_t to unify with the rest of the code.

Since commit 8b41fc4454e ("kbuild: create modules.builtin without
Makefile.modbuiltin or tristate.conf"), MODULE_LICENSE declarations
are used to identify modules. As a consequence, uses of the macro
in non-modules will cause modprobe to misidentify their containing
object file as a module when it is not (false positives), and modprobe
might succeed rather than failing with a suitable error message.
So remove it in the files in this commit, none of which can be built as
modules.

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 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.

For non-english speech synthesis, it is often desirable to make
speakup_soft pass text directly. Adding a direct parameter to the
speakup_soft module allows to easily set that at boot, rather than
setting the sys variable after boot.

Even if speakup does the filtering itself, it does not filter out A_PUNC
characters (because these are needed e.g. for prosody), so we have to tell
synthesizers whether they should filter them out or not.

Pull tty / serial driver updates from Greg KH:
"Here is the big set of tty and serial driver changes for 6.0-rc1.
It was delayed from last week as I wanted to make sure the last commit
here got some good testing in linux-next and elsewhere as it seemed to
show up only late in testing for some reason.
Nothing major here, just lots of cleanups from Jiri and Ilpo to make
the tty core cleaner (Jiri) and the rs485 code simpler to use (Ilpo).
Also included in here is the obligatory n_gsm updates from Daniel
Starke and lots of tiny driver updates and minor fixes and tweaks for
other smaller serial drivers.
All of these have been in linux-next for a while with no reported
problems"

speakupmap.h was not actually intended to be source code, speakupmap.map
is.
This resurrects the makemapdata.c and genmap.c tools to generate
speakupmap.h automatically from the input and speakup headers, and the
speakupmap.map keyboard mapping source file.

- 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.

Users needing it with the dectlk synth report that a 100ms flush delay
is still noticeable and prefer to set it to e.g. 10ms. This leaves the
default to 4000ms (since hitting it is a sign that the cable is faulty
and should be replaced), but allows to set it as short as 10ms.

Since commit a9c3f68f3cd8d (tty: Fix low_latency BUG) in 2014,
tty_flip_buffer_push() is only a wrapper to tty_schedule_flip(). We are
going to remove the latter (as it is used less), so call the former in
the rest of the users.
