ba87f0801d Remove explicit filename from Doxygen @file commands.

documentation in the @file block refers to a file different from the
one the block resides in.

34e52abb62 DECLARE_ALIGNED macro for TMS470 compiler
This compiler supports gcc-style alignment attributes for struct,
but not for global variables.  For the latter, alignment can be
specified with a pragma, which does not work for struct members or
local variables.  By using both pragma and attribute, one or the
other will always take effect.

Unfortunately, no means exists for aligning stack variables.

8a24e98d50 Make DECLARE_ALIGNED macros work with external array specifiers
The macro implementation might need the name of the variable being
declared for compiler-specific syntax.  Moving array specifiers outside
the macro invocation allows this to work.

4ce9492339 Move DECLARE_ALIGNED and DECLARE_ASM_CONST to internal.h.
Their definition depends on preprocessor directives from config.h,
thus they cannot be declared in a public header since public headers
cannot #include config.h.

987903826b Globally rename the header inclusion guard names.
Consistently apply this rule: the guard name is obtained from the
filename by stripping the leading "lib", converting '/' and '.'  to
'_' and uppercasing the resulting name. Guard names in the root
directory have to be prefixed by "FFMPEG_".
