This introduces target/target.h. This file declares some functions that the shared code can use and that clients must implement. It also changes some shared code to use these functions. gdb/ChangeLog: * target/target.h: New file. * Makefile.in (HFILES_NO_SRCDIR): Add target/target.h. * target.h: Include target/target.h. (target_read_memory, target_write_memory): Don't declare. * target.c (target_read_uint32): New function. * common/agent.c: Include target/target.h. [!GDBSERVER]: Don't include target.h. (helper_thread_id): Type changed to uint32_t. (agent_get_helper_thread_id): Use target_read_uint32. (agent_run_command): Always use target_read_memory and target_write_memory. (agent_capability): Type changed to uint32_t. (agent_capability_check): Use target_read_uint32. gdb/gdbserver/ChangeLog: * target.h: Include target/target.h. * target.c (target_read_memory, target_read_uint32) (target_write_memory): New functions.
