cd15b7c03d samplefmt: make av_samples_alloc() initialize the data to silence.
Right now the buffer is zeroed, which does not represent silence for U8(P).

05e209c04c Allow use of strncpy()
There are cases where strncpy() does exactly what is required.
A blanket ban forces more convoluted solutions to be used in those
cases and has been a cause of bugs.

It is similar to av_set_options_string() but accepts a list
of options that can be in shorthand: if the key is omitted
on the first fields, the keys from the shorthand list are
assumed, in order.

cdb7db5acd ARM: align PIC offset pools to 4 bytes
When building Thumb2 code, the end of a function, where the PIC
offsets are placed, need not be aligned.  Although the values
are only accessed with instructions allowing unaligned addresses,
keeping them aligned is preferable.
