directories to SUBDIR.${MK_TESTS} idiom
This is being done to pave the way for future work (and homogenity) in
^/projects/make-check-sandbox .
No functional change intended.
MFC after: 1 weeks
Apply the required sugar to make "make check" just work (tm) when
invoked from a subdirectory where HAS_TESTS is defined in the
relevant Makefile.
Adjust $LD_LIBRARY_PATH and $PATH appropriately from bsd.lib.mk
and bsd.prog.mk to make the "user experience" more out of the
box/seamless.
While here, make the variable immediate to avoid silly mistakes that might
result in wiping out / by accident if the variable is evaluated in a delayed
manner due to poor use of $DESTDIR.
If the user decides to specify HAS_TESTS in the upper directory, "make check"
will now iterate down the "test" directory, running the tests with an assumably
sane default value for $LD_LIBRARY_PATH, $PATH, etc.
The purpose of this work is to simplify "make check" -- in particular, to
increase dev-test velocity and get me (and others who pay attention, like
me) out of the business of paying attention to Jenkins runs and get other
developers to (hopefully) test their code more often prior to commit.
Huge caveat:
Obviously, this will fail miserably when the host can't run the target
architecture/code. Necessary compat layer or qemu usermode will be required
to make this possible, which is outside the scope of this work (batteries
not included).
_FILESMKDIR is an internal knob for creating directories
It's by no means a substitute for mtrees since the semantics for using install
are a bit rudimentary -- it's meant purely to simplify automatic directory creation
without having to invoke "make hier[archy]" from ${SRCTOP} in order to populate
a directory tree.
- bsd.compiler.mk: Must ensure that the CCACHE_WRAPPER_PATH comes first
in PATH.
- Makefile.inc1: Must prepend the CCACHE_WRAPPER_PATH into BPATH as it
overrides the PATH set in bsd.compiler.mk in sub-makes. The PATH
set in bsd.compiler.mk is not exported and doing so would cause it to
then override the BPATH set from environment. The only sane solution
is to prepend into BPATH as needed.
CCACHE_PATH could possibly be used for some of this as well.

Linux specific things to the native fdescfs file system.
Unlike FreeBSD, the Linux fdescfs is a directory containing a symbolic
links to the actual files, which the process has open.
A readlink(2) call on this file returns a full path in case of regular file
or a string in a special format (type:[inode], anon_inode:<file-type>, etc..).
As well as in a FreeBSD, opening the file in the Linux fdescfs directory is
equivalent to duplicating the corresponding file descriptor.
Here we have mutually exclusive requirements:
- in case of readlink(2) call fdescfs lookup() method should return VLNK
vnode otherwise our kern_readlink() fail with EINVAL error;
- in the other calls fdescfs lookup() method should return non VLNK vnode.
For what new vnode v_flag VV_READLINK was added, which is set if fdescfs has beed
mounted with linrdlnk option an modified kern_readlinkat() to properly handle it.
For now For Linux ABI compatibility mount fdescfs volume with linrdlnk option:
mount -t fdescfs -o linrdlnk null /compat/linux/dev/fd

you're already working with sbintime_t units and it's dumb to convert them
to ticks just so they can get converted back to sbintime_t under the hood.

This fixes 'make cleandir' to use the same ordering as 'make cleanobj'.
Meaning that SUBDIR will be recursed before the current directory is
handled. This avoids an 'rm -rf /usr/obj/usr/src/lib/libc' while
a child 'rm -rf /usr/obj/usr/src/lib/libc/tests' is being ran next,
or even removing the current directory and then recursing into a child
and using the 'missing OBJDIR' logic to remove files rather than the
directory.
The most ideal ordering here would be for 'cleanobj' and 'cleandir' to
simply remove the .OBJDIR and then not recurse at all. This is only
safe if it is guaranteed that all children directories have no orphaned
files in their source checkout and are only using obj directories. This
is usually safe from the top-level build targets and when using
WITH_AUTO_OBJ. Improving the build for those cases is coming.

- Only recurse on cleanobj/cleandir if there is no .OBJDIR being used.
If we don't recurse then bsd.obj.mk will just rm -rf the OBJDIR dir.
- When recursing on cleanobj/cleandir don't remove dependfiles/dirs
redundantly from the child and main processes. Meaning '.depend', and
'tags', and '.depend.*' will now only be removed from the main
process.
- Stop recursing on 'cleandepend' since the main process can handle
removing all files via the default glob patterns in CLEANDEPENDFILES.
- This reverts r288201, by readding recursion on 'cleanobj', due to
r291635 changing how bsd.subdir.mk handles recursion.
This is primarily targeting ESTALE NFS errors from rm(1) during a
buildworld but is also a performance optimization as both issues fixed
were redundant anyway.

Also switch the logic to enable this for any non-lld linker, since
filter library support is fairly simple and is very likely supported

Create libdl.so.1 as a filter for libc.so.7 which exports public dl*
functions. The functions are resolved from the rtld instead, the goal
of creating library is to avoid errors from the static linker due to
missed libdl. For static binaries, an empty .o is compiled into
libdl.a so that static binaries still get dl stubs from libc.a.
Right now lld cannot create filter objects, disable libdl on arm64
when binutils are not used.

Note that this doesn't handle a scenario pointed out by rgrimes@:
when the terminal is resized after login, the terminal size won't

Instead of using GID_FT SNS request to get list of registered FCP ports,
use GID_PT to get list of all Nx_Ports, and then use GFF_ID and/or GFT_ID
requests to find whether they are FCP and target capable.
The problem with old approach is that GID_FT does not report ports without
FC-4 type registered. In particular it was impossible to boot OS from
FreeBSD FC target using QLogic FC BIOS, since one does not register FC-4
type even on new cards and so ignored by old code as incompatible.
As a side bonus this allows initiator to skip pointless logins to other
initiators by fetching that information from SNS instead.
In case some switches do not implement GFF_ID/GFT_ID correctly, add sysctls
to disable that functionality. I handled broken GFF_ID of my Brocade 200E,
but there may be other switches with different bugs.
Linux also uses GID_PT, but GFF_ID is disabled by default there, and GFT_ID
is not supported.
