Encoder needs put_bits.h, not get_bits.h

A negative `size' will bypass FFMIN().  In the subsequent memcpy() call,
`size' will be considered as a large positive value, leading to a buffer
overflow.

Change the type of `size' to unsigned int to avoid buffer overflow, and
simplify overflow checks accordingly.

Sanity checks like `data + size >= data_end || data + size < data' are
broken, because `data + size < data' assumes pointer overflow, which is
undefined behavior in C.  Many compilers such as gcc/clang optimize such
checks away.

Use `size < 0 || size >= data_end - data' instead.

The check `start + res < start' is broken since pointer overflow is
undefined behavior in C.  Many compilers such as gcc/clang optimize
away this check.

Use `res > end - start' instead.  Also change `res' to unsigned int
to avoid signed left-shift overflow.

outpicref is not always in synch with showwaves->outpicref, which is
changed as a side effect of the call to functions.

The live flags is currently unused, but still kept for backward
compatibility reasons (and in case it turns to be useful again for
whatever reason).

Fixes bug 431.

The function is known to be missing in at least one target (MSVC).

The function is only used in VP3 and VP5, so no need to have it in
DSPContext.

Documentation copied from asyncts, the options are supposed to do
the same thing. If not please submit a testcase where they differ
so we can fix it.
