When backing up the top-left border, check that the top-left
(rather than left) MB indeed does belong to our slice. If it
doesn't, backing up has no positive effect but may accidentally
interfere with other threads writing in the same space.

Fixes occasional one-off effects when enabling slice-MT.

The prototype should use the same typedefs as the definition, or it
will fail where int32_t is not int (DOS apparently).

This is consistent with how all other table generation programs are named.
Moreover this ensures that the cos table generation program is correctly
deleted when cleaning the tree.

tableprint.c serves little purpose on its own and removing it allows building
the table generator programs with the normal HOSTPROGS Makefile rules.

This collapses the make rules for the trig tables into a pattern
rule.  Based on a patch by Diego, modified to avoid using fragile
make constructs and allow future addition of fixed-point sin tables.

This separation allows these functions to be used in a cleaner
fashion from other codecs (e.g. qdm2) and simplifies creating

This adds a _fixed suffix to the fixed-point versions of things
with both float and fixed-point variants.  This makes it more
consistent with other dual-implementation things, e.g. fft.
