Change int to bool for the relocate_* functions
These parameters are only used as bools. This also renames "flag" to "relocatable" to make it clearer what it does. gdb/ChangeLog: 2019-09-06 Christian Biesinger <email@example.com> * defs.h (relocate_gdb_directory): Change int to bool in signature and rename flag to relocatable. * main.c (relocate_path): Likewise. (relocate_gdb_directory): Likewise.
