fix some global var alignment

[Larice Robert <larice at vidisys dot de>]

this patch annotates approximately 200 global variables
with gcc alignment attributes.

use like this:
  patch -d ${ECOS_REPOSITORY}/.. -p1 < thisfile

(global variables of kind:
   char stack[STACK_SIZE]
   char stack[NTHREAD][STAC_SIZE]
   char mempool[something]
   char space[N*sizeof(class ..)];
)

a new preprocessor define in infra/current/include/cyg_type.h
  CYGBLD_ANNOTATE_ALIGNED 
controls this annotation. it defaults to
   __attribute__ ((aligned))
which means, gcc will align the object so it fulfills
wort-case requirements for any data type of the current
CPU target architecture.

---------------------------

hope this is of any use for somebody,
  its a bit silent on those ecos lists,
especially a bit unidirectional.

have a good day,

Robert Larice
