According to POSIX, strptime() should consume whitespaces in the date
string everytime a whitespace conversion specification is found in the
date format specification. Make av_small_strptime() conform with this
behavior.

In particular, should fix trac ticket #1739.

This prevents lost frames after a resolution change.

Also signal the wait if audio buffer is empty. This fixes jerky audio with

nstreams is assumed to be 1 at that point, so the loop is pointless.

"str" is misleading here (it's often used for string). "sid" makes more
sense to identify a stream id.

There is no point in a distant definition of a small function like this
used only once.

Additional spacing to distinguish better the block.

Fixes compilation with XCode 3.2.6.
Fixes ticket #1736.

Avoid a near infinite loop.

These functions do not benefit from being inlined.  They are large,

It internally decodes as float and then converts to s16 by a call to
float_to_int16(). The caller can do this just as well by using lavr.

Gray8 is not considered to be paletted, so this would cause an invalid
write.

Fixes bug 367.

CC: libav-stable@libav.org

Some implementations of sscanf do not handle a space before a trailing %n
properly.

As an example, MSVC's does this for the second insatnce in this patch, for
an input of "0x3:c0=c1:c1=c0":
    1) Match the final "c0" or "c1".
    2) Realize it's at the end of the string.
    3) Check for %n.
    4) There is no %n, but a space instead.
    5) Leave 'len' unitilialized.

So, move it out of the sscanf format strings, and call skip_spaces instead.

This bug does not affect skip_spaces since %n is the first and only formatting
string.
