Thomas Monjalon 43e73483a4 devtools: forbid variable declaration inside for 
Some compilers raise an error when declaring a variable
in the middle of a function. This is a C99 allowance.
Even if DPDK switches globally to C99 or C11 standard,
the coding rules are for declarations at the beginning
of a block:
http://doc.dpdk.org/guides/contributing/coding_style.html#local-variables

This coding style is enforced by adding a check of
the common patterns like "for (int i;"

The occurrences of the checked pattern are fixed:
	'for *(\(char\|u\?int\|unsigned\|s\?size_t\)'
In the file dpaa2_sparser.c, the fix is to remove the unused macros.
