FIPS -140-3 requires that we give applications a way to restart the Power On Self-Tests programmatically. Unloading the shared library is insufficient. Shutting down softoken and restarting it with a special flag is.
This path accomplishes this task by:
1) adding a new startup flag init argument flag called forcePost which is
parsed at FC_Initialize time.
2) Code which checks if the post ran properly takes a new Bool which tells the function whether or not to rerun the post operations. If post operations are to be rerun, all test flags are set to unknown or fail and the tests are rerun. The results are returned.
3) Public facing functions to verify integrity looks for a special non-valid character flag as the first character of the filename and uses that to decide if we should rerun post or not. Callers add the flag if post should be rerun.
4) pk11mode, the general FIPS test program makes sure we can turn on the forcePost flag.

Redhat has run our scanners on the full NSS tree and identifed 123
errors our security team determined where 'critical'. I've reviewed
the errors and identified a much smaller subset of errors that are
either real, or confusing enough to warrent suppression comments.
Many errors are in cmd and gtest. I've skip those commands red hat does
not ship in this report, and I've skipped the issues in gtest.
Also, There's a large number of leaked_storage errors because evidently
coverity gets confused when you have a pointer in a local variable and
you pass that pointer off to a global or a function variable. I've
skipped most of those as well.
changes:
crlutil.c: add missing arena free in error path. #def4
secutil.c: (Not coverity found) make sure we don't overflow our buffer
in badly encoded ECC oids.
modultil.c: Fix incorrect free operation in pk11install case. #def6
signtool/javascript.c: free old archiveDir after use in PR_smprintf #def8
don't double free curitem (curitem is almost
certainly NULL at this point, so the current code
is a noop). #def9, #def10
signtool/list.c: remove unused ugly_list variable (which is leaked) #def12
signtool/util.c: don't leak 'dir' in error path #def13 #def14
sigver/pk7print.c: coverity: use static pk rather than an allocated and
leaked pointer. #def15
add code for EC
disbled DSA code that isn't actually working
(PQG params).
symkeyutil.c: free name (depends on PORT_Free null check). #def16
pkix_pl_nameconstraints.c: Fix coverity double free warning.
PKIX_ERROR_RECEIVED is almost
certainly false in this case, but by
setting arena to NULL we make
sure it's not used or freed again. #def99
pkix_pl_string.c: Fix varargs leak in the error path. #def109
pk11parse.c: secmod_doDescCopy can reallocate our newSpec, but the
pointer we are passed is an offset from newSpec. Pass in
both pointers and return our newly allocated spec and
length in that case.#def113
cmsutil.c: suppress cppcheck warnings do to cmsutil use of unions to
cast pointers. #def113-117
pkcs11.c: support coverity incorrect use_after_free warning. #def118

Copying private headers is now simply included in the exports
target, as these headers use an extra directory anyway.

Add ZLIB_INCLUDE_DIR variable
On Linux platform[1], the build system forces to use zlib from the
system instead of compiling the one located intree.
The following error is raised when the zlib header is installed
somewhere else than in the default system include path:
ssl3con.c:39:18: fatal error: zlib.h: No such file or directory
#include "zlib.h"
The same trick setup for sqlite include directory is reproduced for
zlib. The build system disallows in any manner to give arguments to the
compiler explicity.
The variable ZLIB_INCLUDE_DIR point to the directory where the zlib
header is located.

These files were being reformatted by clang-format 4.0. If you make this
change, then both 3.9 (in CI) and 4.0 are happy with the result. I don't plan
to do this often, but it is a huge help.
Note that the PK11 ECDSA tests are an odd duck, I have more on that coming.
