93fb037d84 Compile IPA modules with C11 extensions
- define __STDC_WANT_LIB_EXT1__ to get C11 extensions like memset_s() for
  Samba's ZERO_STRUCT() macro, see
  https://en.cppreference.com/w/c/string/byte/memset
- _DEFAULT_SOURCE enables features like htole16() from endian.h, see
  http://man7.org/linux/man-pages/man3/endian.3.html
- _POSIX_C_SOURCE >= 200809 enables features like strndup() from string.h,
  see http://man7.org/linux/man-pages/man3/strndup.3.html
- time_t is no longer implicitly defined, include time.h
- typeof() is only available as GNU extension. Use explicit types
  instead of generic __typeof__().

c9c58f2d35 Fix OTP validation in FIPS mode
NSS doesn't allow keys to be loaded directly in FIPS mode. To work around
this, we encrypt the input key using an ephemeral key and then unwrap the
encrypted key.

b7329e31f5 slapi plugins: fix CFLAGS
Add explicit NSPR_CFLAGS and NSS_CFLAGS where NSPR_LIBS and NSS_LIBS is
used.

Use DIRSRV_CFLAGS rather than hardcode -I/usr/include/dirsrv.

Append NSPR_CFLAGS to DIRSRV_CFLAGS in ./configure as slapi-plugin.h
includes nspr.h.

d5683726d2 Build: remove incorrect use of MAINTAINERCLEANFILES
Automake manual section 13 What Gets Cleaned says that make maintainer-clean
should not remove files necessary for subsequent runs of ./configure.

It practically means that all usage of MAINTAINERCLEANFILES were incorrect
so I've removed them.

This is step forward working VPATH builds which cleanly separate sources
and build artifacts. It makes the system cleaner and easier to

Python and web UI likely require more work to make VPATH builds working.

9e3eeadeb3 Fix an integer underflow bug in libotp
Temporarily storing the offset time in an unsigned integer causes the
value of the offset to underflow when a (valid) negative offset value
is generated. Using a signed variable avoids this problem.

d3638438fc Add TOTP watermark support
This prevents the reuse of TOTP tokens by recording the last token
interval that was used. This will be replicated as normal. However,
this patch does not increase the number of writes to the database
in the standard authentication case. This is because it also
eliminates an unnecessary write during authentication. Hence, this
patch should be write-load neutral with the existing code.

Further performance enhancement is desired, but is outside the
scope of this patch.
