51369649b0 sys: further adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 3-Clause license.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.

1dc349ab95 prefix UFS symbols with UFS_ to reduce namespace pollution
Specifically:
  ROOTINO -> UFS_ROOTINO
  WINO -> UFS_WINO
  NXADDR -> UFS_NXADDR
  NDADDR -> UFS_NDADDR
  NIADDR -> UFS_NIADDR
  MAXSYMLINKLEN_UFS[12] -> UFS[12]_MAXSYMLINKLEN (for consistency)

Also prefix ext2's and nandfs's NDADDR and NIADDR with EXT2_ and NANDFS_

fca15474a0 ext2fs: renumber the license clauses to avoid skipping #3.
This is to keep consistency with other files, and help license-checking
utilities determine the number of clauses that apply.

No functional change.

70097aac13 Define ext2fs local types and use them.
Add definitions for e2fs_daddr_t, e4fs_daddr_t in addition
to the already existing e2fs_lbn_t and adjust them for ext4.
Other than making the code more readable these changes should
fix problems related to big filesystems.

Setting the proper types can be tricky so the process was
helped by looking at UFS. In our implementation, logical block
numbers can be negative and the code depends on it. In ext2,
block numbers are unsigned so it is convenient to keep
e2fs_daddr_t unsigned and use the complete 32 bits. In the
case of e4fs_daddr_t, while the value should be unsigned, for
ext4 we only need to support 48 bits so preserving an extra
bit from the sign is not an issue.

While here also drop the ext2_setblock() prototype that was
never used.

da057ed2d3 Define and use e2fs_lbn_t in ext2fs.
In line to what is done in UFS, define an internal type
e2fs_lbn_t for the logical block numbers.

This change is basically a no-op as the new type is unchanged
(int32_t) but it may be useful as bumping this may be required
for ext4fs.

Also, as pointed out by Bruce Evans:

-Use daddr_t for daddr in ext2_bmaparray(). This seems to
improve reliability with the reallocblks option.
- Add a cast to the fsbtodb() macro as in UFS.

b6113fb31a Re-sort ext2fs headers to make things easier to find.
In the ext2fs driver we have a mixture of headers:

- The ext2_ prefixed headers have strong influence from NetBSD
and are carry specific ext2/3/4 information.
- The unprefixed headers are inspired on UFS and carry implementation
specific information.

Do some small adjustments so that the information is easier to
find coming from either UFS or the NetBSD implementation.

f744956b4a Relax some unnecessary unsigned type changes in ext2fs.
While the changes in r245820 are in line with the ext2 spec,
the code derived from UFS can use negative values so it is
better to relax some types to keep them as they were, and
somewhat more similar to UFS. While here clean some casts.

Some of the original types are still wrong and will require
more work.

1d04725a7a ext2fs: make some inode fields match the ext2 spec.
Ext2fs uses unsigned fields in its dinode struct.
FreeBSD can have negative values in some of those
fields and the inode is meant to interact with the
system so we have never respected the unsigned
nature of most of those fields.

Block numbers and the NFS generation number do
not need to be signed so redefine them as
unsigned to better match the on-disk information.

9e880b876d Sync with several changes in UFS/FFS:
- 77115: Implement support for O_DIRECT.
- 98425: Fix a performance issue introduced in 70131 that was causing
  reads before writes even when writing full blocks.
- 98658: Rename the BALLOC flags from B_* to BA_* to avoid confusion with
  the struct buf B_ flags.
- 100344: Merge the BA_ and IO_ flags so so that they may both be used in
  the same flags word. This merger is possible by assigning the IO_ flags
  to the low sixteen bits and the BA_ flags the high sixteen bits.
- 105422: Fix a file-rewrite performance case.
- 129545: Implement IO_INVAL in VOP_WRITE() by marking the buffer as
  "no cache".
- Readd the DOINGASYNC() macro and use it to control asynchronous writes.
  Change i-node updates to honor DOINGASYNC() instead of always being
  synchronous.
- Use a PRIV_VFS_RETAINSUGID check instead of checking cr_uid against 0
  directly when deciding whether or not to clear suid and sgid bits.

e09c00cada Bring in the ext2fs work done by Aditya Sarawgi during and after Google Summer
of Code 2009:

- BSDL block and inode allocation policies for ext2fs. This involves the use
  FFS1 style block and inode allocation for ext2fs. Preallocation was removed
  since it was GPL'd.
- Make ext2fs MPSAFE by introducing locks to per-mount datastructures.
- Fixes for kern/122047 PR.
- Various small bugfixes.
- Move out of gnu/ directory.
