This series continues reducing fs/ext4l/ext4_uboot.h by moving more
definitions to appropriate include/linux/ header files.

The previous series reduced the file from 2584 to 1980 lines. This
series further reduces it to 1816 lines (total 30% reduction).

New headers created:
- fiemap.h: FIEMAP extent types and fiemap_extent_info structure
- statfs.h: kstatfs structure for filesystem statistics
- exportfs.h: NFS export operations (fid, export_operations)
- mbcache.h: Metadata block cache stubs
- wait_bit.h: Wait bit operation stubs
- ratelimit.h: Rate limiting stubs
- projid.h: Project ID type (kprojid_t)
- mnt_idmap.h: Mount ID mapping stub
- hash.h: hash_64() and hash_32() functions
- blockgroup_lock.h: Block group lock structure
- delayed_call.h: Delayed function call support

Updated headers:
- capability.h: Added CAP_SYS_ADMIN
- uio.h: Added kiocb and IOCB_* flags
- utsname.h: Added init_utsname() function
- proc_fs.h: Added proc_ops structure and procfs stubs

All implementations are appropriate stubs for U-Boot's single-threaded
environment. Tests pass with these changes.

  linux: capability: Add CAP_SYS_ADMIN constant
  linux: uio: Add kiocb struct and IOCB_* flags
  linux: Add fiemap.h header with extent mapping types
  linux: Add statfs.h header with kstatfs struct

  linux: Add mbcache.h header with metadata cache stubs
  linux: Add wait_bit.h header with wait bit stubs
  linux: Add ratelimit.h header with rate limiting stubs
  linux: utsname/proc_fs: Add init_utsname() and proc_ops
  linux: Add projid.h and mnt_idmapping.h headers
  linux: Add hash.h header with hash_64 function
  linux: Add blockgroup_lock.h and delayed_call.h headers
