gdb: make structured core file mappings processing global
In corelow.c, within core_target::build_file_mappings, we have code
that wraps around a call to gdbarch_read_core_file_mappings and
provides more structure to the results.
Specifically, gdbarch_read_core_file_mappings calls a callback once
for every region of every mapped file. The wrapper code groups all of
the mappings for one file into an instance of 'struct mapped_file',
this allows all of the mapped regions to be associated with the
build-id and filename of a file.
In the next commit I plan to make this information available via the
Python API, and so I need to allow access to this structured wrapping
outside of corelow.c.
This commit renames 'struct mapped_file' to 'struct core_mapped_file'
and moves the struct into gdbcore.h. Then a new global function
gdb_read_core_file_mappings is created into which I move the code to
build the structured data.
Then corelow.c is updated to call gdb_read_core_file_mappings.
This commit does not extend the Python API, that is for the next
commit.
There should be no user visible changes after this commit.
