realloc() does not accept pointers from memalign().

These help avoiding overflows and simplify error handling.

Also extend documentation accordingly.

In particular, mention the fact that the amortized element addition cost
is constant.

With unknown attribute warnings disabled, these checks are no
longer needed.  Removing them improves readability while having
no effect on generated code.

These macros are redundant.  All uses are replaced with the generic
DECLARE_ALIGNED macro instead.

These macros naturally belong next to the generic DECLARE_ALIGNED
macro.

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.

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.
