Rename TARGET_XFER_E_UNAVAILABLE to TARGET_XFER_UNAVAILABLE
Nowadays, TARGET_XFER_E_UNAVAILABLE isn't regarded as an error in to_xfer_partial interface, so _E_ looks odd. This patch is to replace TARGET_XFER_E_UNAVAILABLE with TARGET_XFER_UNAVAILABLE, and change its value from -2 to 2. Since there is no comparison on the value of 'enum target_xfer_status', so it should be safe. gdb: 2014-02-24 Yao Qi <yao@codesourcery.com> * target.h (enum target_xfer_status) <TARGET_XFER_E_UNAVAILABLE>: Rename it to ... <TARGET_XFER_UNAVAILABLE>: ... it with setting value 2 explicitly. New. * corefile.c (memory_error_message): User updated. * exec.c (section_table_read_available_memory): Likewise. * record-btrace.c (record_btrace_xfer_partial): Likewise. * target.c (target_xfer_status_to_string): Likewise. (raw_memory_xfer_partial): Likewise. (memory_xfer_partial_1, target_xfer_partial): Likewise. * valops.c (read_value_memory): Likewise. * exec.h: Update comments.
