When a new voice is selected, we set volume and pitch appropriate for
the voice. We need to use the numeric index corresponding to the
voice when indexing into the volume and pitch tables, rather than
the raw user input that was used to select the voice.
Note that using the raw input can also lead to an invalid memory read
in the case of invalid or malicious user input.

Well, there is no need to use strcmp since we can make a test of similar semantic by using the var_id field of param.
I moved the test into the VAR_NUM:VAR_TIME case since VAR_STRING will never be "voice".
spk_xlate isn't used anymore (in line 628), then there is no difference between using cp and buf in VAR_STRING case.
Besides, buf is a const char and those changes remove one uneeded line.
I created the function spk_reset_default_value because it clarifies the code and allows code reusing.

Fix up trivial conflicts, mostly just due to the TTY config option
clashing with the EXPERIMENTAL removal.
The PPS (Pulse-Per-Second) line discipline has developed a number of
unhealthy attachments to core tty data and functions, ultimately leading
to its breakage.
The previous patches fixed the crashing. This one reduces coupling further
by eliminating the timestamp parameter from the dcd_change ldisc method.
This reduces header file linkage and makes the extension more generic,
and the timestamp read is delayed only slightly, from just before the
ldisc->ops->dcd_change method call to just after.

For the affected mallocs around these OOM messages:
Converted kzallocs with multiplies to kcalloc.
Converted kmallocs with multiplies to kmalloc_array.
Converted a kmalloc/strlen/strncpy to kstrdup.
Moved a spin_lock below a removed OOM message and
