This patch makes some small cleanups to the declaration of YYLTYPE,
YYLLOC_DEFAULT and related things.
- We used to use undocumented magic #defines for bison,
YYLTYPE_IS_DECLARED and YYLTYPE_IS_TRIVIAL. This may not be
portable across bison versions. Instead define YYLTYPE as a
macro in terms of struct srcpos, as the info pages suggest.
- Our kernel-derived coding style discourages typedefed
structures. So use 'struct srcpos' instead of 'srcpos'
throughout'.
- Indent the YYLLOC_DEFAULT macro according to our coding
style (it was in GNU indent style, since it was taken from
the example in the bison info).
