i#2522 strcasestr prototype error: Remove `const` from result type (D…

…ynamoRIO#2526)

The definition of strcasestr is

char *strcasestr(const char *text, const char *pattern);

but drmemory uses

const char *strcasestr(const char *text, const char *pattern);

This causes build errors when both /usr/include/string.h and
common/utils.h are included in linux. The definition for strcasestr for
C has always not had the `const` in the result type (going back to its
original addition to glibc in 1997). Thus we're pretty safe in not
breaking anything on *nix. The other main use case of drmemory's
strcasestr is on Windows, which does not have strcasestr.

Tested:
$ cmake && make
Also, there are failures in the clang and x86 workflows, but comparing
the logs before/after
shows all failures pre-exist this patch, no new failures.

Here is the complete audit, all failures are pre-existing.

Recorded (errantly) as i#1938 failures:
  - wrap_operators: "internal crash" (Received SIGSEGV)
    - filed as DynamoRIO#2535
  - wrap_cs2bug: CHECK_TRUNCATE_TYPE_sbyte(new_offs) (DynamoRIO#2342)
- pcache-use: "Usage error: meta-instr faulted? must set translation
field and handle fault!" (DynamoRIO#2202)
  - app_suite: vsyscall incorrect assumption (DynamoRIO#2491)
- app_suite.pattern: assert failure: save->ignore_next_delete == 0
(premature deletion)
    - filed as i#2537
  - fuzz_threads: vsyscall incorrect assumption (DynamoRIO#2491)

Note: The above are marked as expected failures but [runsuite_wrapper.pl
hardwires the addition of "i#1938" to test
output](https://github.com/DynamoRIO/drmemory/blob/master/tests/runsuite_wrapper.pl#L281).
DynamoRIO#2534

Not currently recorded as expected failures (all DynamoRIO#2491 - vsyscall
incorrect assumption):
  - selfmod
  - syscalls_unix
  - clone
  - pthread_test
  - realloc

i#2498 init failures: Ignore privlib init failures (DynamoRIO#2515)

Updates DR to 51b152fa2 extends the private loader bcrypt.dll entry
failure being ignored to ignore all private library entry failures. We
have had multiple cases of initializers failing without fatal
consequences, and given that we do not have resources to track down
every detail it is best to note the failure and move on. We have seen
Dr. Memory in particular fail on newer Windows versions and in some
cases ignoring that failure lets the tool continue and succeed, as only
a small piece of the private library is needed (generally pulled in as a
chain of dependences from dbghelp.dll which is used for symbol
information). The private loader on Windows is considered best-effort at
this point.

Issue: DynamoRIO#2498

Update WIX version to 6.14 (DynamoRIO#2497)

Updates the PATH of our Windows builds to find the new WIX version on the
GA CI VM's.

DRi#6611: Fix glibc 2.37 elfutils hang (DynamoRIO#2495)

Updates DR to b42b82b1d to fix a problem with DR's private loader with
glibc 2.37 and the new elfutils libdw when addresses are looked up.

Issue: DynamoRIO/dynamorio#6611

Update DR and fix associated DR and recent-Linux issues (DynamoRIO#2484)

Updates DR to bbd4ffadd.

Fixes several issues with the latest DR and recent Linux platforms:

+ DWARF5 is now the gcc default but is not supported (DynamoRIO#2485) so we add
  -gdwarf-4 to our test flags and the docs.

+ Adds Linux syscall entries for rseq and getrandom, seen on tiny apps now.

+ Fixes a bug in the size of kernel_sigset_t which was resulting in
  false positive uninitialized errors in rt_sigaction.

+ Updates drltrace code for droption now being in a namespace.

+ Adds --recursive to the git submodule commands to get minizip for
  the DR build.

+ Relaxes the drltrace tests to allow __IO_puts and __open.

Update to version 2.6.0 (DynamoRIO#2486)

Updates from 2.5.xx to 2.6.xx.

Fix VS2019 warnings in drcachesim (DynamoRIO#2474)

Updates DR to 1f40176ae to fix VS2019 warnings.
Sets AUTOMATED_TESTING to enable settings in the DR build.

Issue: DynamoRIO/dynamorio#5767

Fix glibc 2.35 rseq issues (DynamoRIO#2470)

Pulls in a fix for DynamoRIO/dynamorio#5431 where the rseq feature in
glibc 2.35 broke DR's rseq support.

i#2467: Document libunwind8 dependence (DynamoRIO#2468)

Add to the Linux installation docs that libunwind8 needs to be installed.
