[PATCH] Use size_t in gdb_bfd_section_data

[PATCH] Use size_t in gdb_bfd_section_data

[Tom Tromey]

BFD recently changed bfd_mmap to use size_t, not bfd_size_type.  This
patch updates gdb_bfd_section_data to follow.  Without this patch, if
the two types ever differ, gdb would fail to build.

My macos CI job (build only) has been failing since that commit, I'm
pretty sure it's related:

/Users/jenkins/build/workspace/binutils-gdb_master_macosbuild/platform/macos-amd64/target_board/unix/src/binutils-gdb/gdb/gdb_bfd.c:800:23: error: no matching function for call to 'bfd_mmap'
          descriptor->data = bfd_mmap (abfd, 0, descriptor->size, PROT_READ,
                             ^~~~~~~~
../bfd/bfd.h:2771:7: note: candidate function not viable: no known conversion from 'bfd_size_type *' (aka 'unsigned long long *') to 'size_t *' (aka 'unsigned long *') for 8th argument
void *bfd_mmap (bfd *abfd, void *addr, size_t len,
      ^

With the hope that it will fix it:
