Fix the following build warn removing unnecessary clean target
from the Makefile. lib.mk handles clean.
Makefile:10: warning: overriding recipe for target clean
../lib.mk:124: warning: ignoring old recipe for target clean
In addition, fix to use TEST_GEN_PROGS for generated test executables
and TES_PROGS for the shell script. Ger rid of all target as lib.mk
handles it.

Rather than trying to guess which implementation of "echo" to run with
support for "-ne" options, use "printf" instead of "echo -ne". It
handles escape characters as a standard feature and it is widespread
among modern shells.

Since commit a1d6cd88c897 ("selftests/ftrace: event_triggers: wait
longer for test_event_enable") introduced bash specific "=="
comparation operator, that test will fail when we run it on a
posix-shell. `checkbashisms` warned it as below.
possible bashism in ftrace/func_event_triggers.tc line 45 (should be 'b = a'):
if [ "$e" == $val ]; then
This replaces it with "=".

When testing with FLAG_DEBUG enabled client, it emits the following

Find the actual echo binary using $(which echo) and use it for
formatted output with -ne. On some systems, the default echo command
doesn't handle the -e option and the output looks like this (arm64
build):
-ne Emit Tests for alsa
-ne Emit Tests for amd-pstate
-ne Emit Tests for arm64
This is for example the case with the KernelCI Docker images
e.g. kernelci/gcc-10:x86-kselftest-kernelci. With the actual echo
binary (e.g. in /bin/echo), the output is formatted as expected (x86
build this time):
Emit Tests for alsa
Emit Tests for amd-pstate
Skipping non-existent dir: arm64
Only the install target is using "echo -ne" so keep the $ECHO variable
local to it.

Use $(KHDR_INCLUDES) as lookup path for installed kernel headers rather
than using kernel headers in include/uapi from the source kernel tree

Remove bogus ../../../../include/ from the search path, because
kernel source headers are not needed by those user-space selftests, and
it causes issues because -I paths are searched before -isystem paths,
and conflicts for files appearing both in kernel sources and in uapi
headers with incompatible semantics (e.g. types.h).

Pull memblock revert from Mike Rapoport:
"Revert 'mm: Always release pages to the buddy allocator in
memblock_free_late()'
The pages being freed by memblock_free_late() have already been
initialized, but if they are in the deferred init range,
__free_one_page() might access nearby uninitialized pages when trying
to coalesce buddies, which will cause a crash.
A proper fix will be more involved so revert this change for the time
being"

The kernel maintains three markers for the MDB dump:
1. The last bridge device from which the MDB was dumped.
2. The last MDB entry from which the MDB was dumped.
3. The last port-group entry that was dumped.
Add test cases for large scale MDB dump to make sure that all the
configured entries are dumped and that the markers are used correctly.
Specifically, create 2 bridges with 32 ports and add 256 MDB entries in
which all the ports are member of. Test that each bridge reports 8192
(256 * 32) permanent entries. Do that with IPv4, IPv6 and L2 MDB
entries.
On my system, MDB dump of the above is contained in about 50 netlink
messages.
Example output:
# ./bridge_mdb.sh
[...]
INFO: # Large scale dump tests
TEST: IPv4 large scale dump tests [ OK ]
TEST: IPv6 large scale dump tests [ OK ]
TEST: L2 large scale dump tests [ OK ]

To get useful results from the Memory Sanitizer, all code running in a
process needs to be instrumented. When building tests with other
sanitizers, it's not strictly necessary, but is also helpful.
So make sure runqslower and libbpf are compiled with SAN_CFLAGS and
linked with SAN_LDFLAGS.

Memory Sanitizer requires passing different options to CFLAGS and
LDFLAGS: besides the mandatory -fsanitize=memory, one needs to pass
header and library paths, and passing -L to a compilation step
triggers -Wunused-command-line-argument. So introduce a separate
variable for linker flags. Use $(SAN_CFLAGS) as a default in order to
avoid complicating the ASan usage.

Using HOSTCC="ccache clang" breaks building the tests, since, when it's

"clang" is considered a target. Fix by quoting it, and also HOSTLD and

Add the fib_rule6_send and fib_rule4_send tests to verify that DSCP
values are properly taken into account when UDP or TCP sockets try to
connect().
Tests are done with nettest, which needs a new option to specify
the DS Field value of the socket being tested. This new option is
named '-Q', in reference to the similar option used by ping.

A couple of tests roll their own auto-allocating file read logic.
Add a generic implementation and convert them to use it.

Add helper functions to read and write (unsigned) long values directly
from/to files. One of the kernel interfaces uses hex strings, so we need
to allow passing a base too.

Often a file is expected to hold an integral value. Existing functions
will use a C stdlib function like atoi or strtol to parse the file.
These operations are error prone, with complicated error conditions
(atoi returns 0 if not a number, and is undefined behaviour if not in
range. strtol returns 0 if not a number, and LONG_MIN/MAX if not in
range + sets errno to ERANGE).
