[bug-gawk] [PATCH] Move init_debug() and debug_prog() prototypes to awk.h

[Adrian Bunk]

Michael Tautschnig noticed a mismatch in the return type
of init_debug(), thankfully harmless since the current
user does not check it.

Move the init_debug() and debug_prog() prototypes to awk.h
to enable the compiler to do signature checking.
