Sean McGovern 87a74f478f configure: disable hardware capabilities ELF section with suncc on Solaris x86 
When using suncc to build, the Solaris linker will mark
an executable with each instruction set encountered by
the Solaris assembler.  As our libraries contain their own
guards for processor-specific code, instead suppress
generation of the HWCAPS ELF section on Solaris x86 only.

Stefano Sabatini 163854bca0 vf_drawtext: drop text wrapping feature 
Or in other word, do not go to the next line when the text cannot be
rendered within the frame.

The rationale is that wrapping is hard to manage, as it depends on the
position of the text, thus making hard/impossible to compute the size
occupied by the rendered text, and makes the filter behavior
unpredictible with moving text (implemented in a pending patch).

Also the current wrapping code is very limited (for example it splits
words in the middle), and correctly handling wrapping requires much
more complexity (alignment, gravity, word parsing etc.), while
drawtext is meant to be only a thin wrapper around libfreetype, so
such advanced features don't belong here.
