core/conv/conv_acc.c: use static allocation for trellis
Allocation of a new memory is an expensive operation, which
takes place when it's initially unknown, how much memory will
we need, or in order to decrease total memory usage.
The trellis struct wasn't require dynamic allocation itself,
so let's allocate one statically inside the vdecoder structure.

core/conv/conv_acc.c: delete reset_decoder()
Currently this implementation exposes nothing than
osmo_conv_decode_acc(), so it wasn't possible to call
reset_decoder() from outside.
The method itself was used to initialize accumulated
path metrics and the starting state of encoder. Now
this code is moved to generate_trellis().
Moreover, setting accumulated path metrics inside
existing loop is a bit faster that calling memset().

core/conv: use proper filenames
We already have generic convolutional transcoding implementation
written by Sylvain Munaut and named 'conv.c', so 'viterbi_*' names
looked a bit confusing.
Let's use a single naming scheme for Viterbi related code.
