Touch attribute file to fix errors like:
Can't open ./demoCA/index.txt.attr for reading,
No such file or directory

Until https://github.com/rr-debugger/rr/issues/2613
has been addressed, ./mtr --rr will fail to start up the
server if it has been configured with liburing.
To make the ./mtr --rr option work out of the box, we will
disable native asynchronous I/O.
Note: libaio never worked under rr, but it failed more gracefully:
the emulated io_setup() call would always return an error.
use _RR_TRACE_DIR=dir instead of -o dir, as the former can store
multiple traces in dir (if, e.g., the test restarts mysqld)
suppress uninitialized warning when $exe is undefined (--manual-XXX)
add a new "debugger" to mtr, that runs the executable
under valgrind in gdb. valgrind pid is auto-detected,
but the delay (sleep) and vgdb path are hard-coded for now
"debugger" is anything that wraps execution of a target
binary (mysqld or mysqltest). Currently the list includes:
gdb, ddd, dbx, lldb, valgrind, strace, ktrace, rr,
devenv, windbg, vsjitdebugger.
for every debugger xxx, mtr will recognize four options:
--xxx, --boot-xxx, --manual-xxx, --client-xxx.
They all support an optional "=string" argument. String
being a semicolon-separated list of commands (e.g. for gdb)
or one (not semicolon-separated) command line of options
(e.g. for valgrind). Or both (e.g. --gdb='-quiet -nh;info files'
In embedded both --xxx and --client-xxx work.
Functionality changed/removed:
* --rr-args is gone
* --rr-dir is gone
* --manual-debug is gone
* --debugger={devenv|vc|windbg|vc_express|vsjitdebugger} is gone
* --strace-option is gone
* --stracer={strace|ktrace} is gone
* --valgrind only enables it for the server, not for everything
* --valgrind-all is gone
* --valgrind-mysqltest is gone
* --valgrind-mysqld is gone
* --valgrind-options is gone
* --valgrind-option is gone
* --valgrind-path is gone
* --callgrind is gone
* one cannot combine --valgrind --gdb anymore
* valgrind report doesn't add a fake test line to the output
* vc and vcexpress on windows are no longer supported
Explicitly setting encoding to UTF-8 when writing to file and
replacing wide characters from MTR_RES_FAILED when writing to
XML file. The wide characters are not allowed in XML.
* use the environment variable HA_S3_SO, not a literal ha_s3 in cnf files
* make ConfigFactory to support empty option values
* update no_s3.result after MDEV-11412
On FreeBSD, perl isn't in /usr/bin, its in /usr/local/bin or
elsewhere in the path.
Like storage/{maria/unittest/,}ma_test_* , we use /usr/bin/env to
find perl and run it.
Replace all references to /usr/sbin/mysqld (and bin and libexec) with
mariadbd, so that the binary server will always be 'mariadbd'.
Also update all places that reference the server binary in other ways,
such as AppArmor profiles and scripts that previously expected to find
a 'mysqld' in process lists.
