Revert r330897:

This was intended to be a non-functional change. It wasn't. The commit
message was thus wrong. In addition it broke arm, and merged crypto
related code.

Revert with prejudice.

This revert skips files touched in r316370 since that commit was since
MFCed. This revert also skips files that require $FreeBSD$ property
changes.

Thank you to those who helped me get out of this mess including but not
limited to gonzo, kevans, rgrimes.

Partial merge of the SPDX changes

These changes are incomplete but are making it difficult
to determine what other changes can/should be merged.

No objections from: pfg

Copy head@r302406 to stable/11 as part of the 11.0-RELEASE cycle.
Prune svn:mergeinfo from the new branch, as nothing has been merged
here.

Additional commits post-branch will follow.

Add missing static qualifiers

MFC After: 3 days

Put some static keywords in the source code.

For these simple utilities, it doesn't harm to make all global variables
static. In fact, this allows the compiler to perform better forms of
optimisation and analysis.

Adhere to POSIX: the -m option only applies to the newly created
directories; it should not change the permission bits of already
existing directories.

Fix a bug introduced in rev.1.23 - for some reason mkdir("/", ...) system
call returns `EISDIR', not `EEXIST', so that be prepared for that. This should
fix number of ports, that often call `mkdir -p //usr/local/foobar'. This
is just a quick workaround, the real fix would be either to avoid calling
mkdir("/", ...) or fix VFS code to return consistent errno for this case.

Special case the error reporting when errno is ENOTDIR or ENOENT.

This makes "mkdir /nonexistant/foo" complain that /nonexistant
doesn't exist rather than /nonexistant/foo which doesn't make much
sense.

Fix behaviour for 'mkdir -m 777 / /tmp/foo'. Play "guess the style bug"

Reported by: bde

Honour the spirit rather than the implementation of the previous changes;
if we are invoked with -m, use chmod() on the final directory component
in order to ensure the mode is correctly set.

Make this compile, and honour the spirit of the original design while
incorporating the intended fix. Attempt to address some of the

correct use of .Nm. Add rcsid.

Fix several problems with mkdir:

1) Fix mkdir -p to exit with the proper exit status and issue an error
message if it was unable to create all of the specified directories
and they did not previously exist. POSIX says:

The mkdir utility shall exit with one of the following values:

0 All the specified directories were created successfully or the
-p option was specified and all the specified directories now
exist.

E.g.

% mkdir -p /var/mkdir
mkdir: /var/mkdir: Permission denied

% touch /tmp/file
% mkdir -p /tmp/file/dir
mkdir: /tmp/file: Not a directory

Previously the above examples would exit with a zero exit status
and no error message. Something like the following run as a
normal user will still not produce an error:

% id
uid=629(mpp) gid=629(mpp)....
% mkdir -p /usr/local/etc
% ls -ld /usr/local/etc
drwxr-xr-x 4 bin bin 512 Dec 26 14:55 /usr/local/etc/

2) Cleaned up the mode handling to be more efficient when multiple
directories are being created.

3) Fixed a problem where directories could be created with the wrong mode
if the the -p option was specified and the build() routine returned
and error. It would leave the umask set incorrectly at this point.

4) Removed an unused variable.

Closes PR# 2304.

compare return value from getopt against -1 rather than EOF, per the final
posix standard on the topic.

[ From Dave Tweten ]

POSIX.2 looks pretty unequivocal to me, and it agrees with you.

Under the explanation of the "-p" option, it says, "Each dir operand that
names an existing directory shall be ignored without error." Under the
explanation of exit status zero, it says, "All the specified directories were
created successfully, or the-p option was specified and all the specified
directories now exist."

Seems to me POSIX requires exactly the behavior you want.

[ And I've made the change, which is also now compatible with 1.x - jkh ]
