Use an helper function to seek by sector to avoid possible mistakes
due shifting by WTV_SECTOR_BITS a 32bit integer.

Contrary to common intuition, a 32 bit integer left shifted
by a 64 bit integer does not promote the 32 bit integer to
64 bit before shifting.

Improve interface flexibility. In particular makes it possible to set
channel layout through symbolic names using the av_opt_set() interface.

A few fate instances on OS/2, OpenBSD, FreeBSD and IA64 linux currently
still fail a few tests with a maxdiff of 6.

The new type is compatible with AV_OPT_TYPE_INT64, but allows to specify
channel layouts using the format accepted by av_get_channel_layout().

The new syntax is preferred since it allows backward syntax compatibility
with libswr when switching to the new option handling code with
AV_OPT_TYPE_CHANNEL_LAYOUT.

With the new parser the string:
1234

is interpreted as a channel layout mask, rather than as a number of
channels, and thus it's compatible with the current way to set a channel
layout as an integer (e.g. for the icl and ocl options) making use of
integer option values.

ff_get_channel_layout() with compat=0 will be used in the
AV_OPT_TYPE_CHANNEL handler code.

The user is encouraged to switch to the new forward compatible syntax,
which requires to put a trailing "c" when specifying a layout as a number
of channels.

In particular, do not set default string value by hand and use
av_opt_free() to free context.

This makes sure that pointers from av_strdup are reallocable,
which is used in av_dict_set if the AV_DICT_APPEND flag is set.

Nothing should rely on pointers from av_strdup being aligned.
