Clang complains if eiher one of those linker flags are used during compilation:
clang-9: error: -Wl,-z,relro: 'linker' input unused [-Werror,-Wunused-command-line-argument]
clang-9: error: -Wl,-z,now: 'linker' input unused [-Werror,-Wunused-command-line-argument]
This patch applies those flags only when linking.

Cygwin's linker does not support -Wl,-z,relro and -Wl,-z,now and
AC_COMPILE_IFELSE did only compile but not link, so it wouldn't detect
whether these flags are supported. So, use AC_LINK_IFELSE to detect
support for these flags.

Get rid of the 'c' code that only changed the user and add for support of
the --runas option to change to a different user in the python part.
To get 'make distcheck' to work I needed to name the swtpm_setup python
script with the suffix .in so that it gets copied to the build directory
as swtpm_setup. We need to change execute permissions on this file after
copying.

Switch over to the new python implementation of swtpm_setup. We need to
also adjust test cases that involved the tcsd that otherwise fail for
various reasons. For in-place testing we need to adjust the PYTHONPATH
and PATH so that swtpm_setup.py can be found and so that swtpm_setup.py
then finds swtpm if it is not explicitly passed as parameter.
Adjust the man page for swtpm_setup to reflect the changes.
We now can run swtpm_setup as any user. However, libvirt still runs it
as tss:tss (for example), which is then creating the signing key as tss:tss
as well. Ideally libvirt would run it as tss:root or any other combination
since the tss group may be used for user wanting to access /dev/tpmrm0 for
example. We at least change the directory ownership of /var/lib/swtpm-localca
to tss:root and keep the world out of this directory.

Rewrite swtpm_setup.sh in python. Use a permanent connection from the
tool to swtpm via passing file descriptors of a unix socketpair. Implement
all functionality in python so that we don't rely on trousers and tpm-tools
for swtpm_setup. This now allows any user to setup a TPM 1.2 whereas before
it had to be root or the tss user.

A typo in the condition meant that netstat was always required regardless of

Signed-off-by: Jonas Witschel <diabonas@archlinux.org>
If the tcsd (trousers) is available, TPM 1.2 support should work as well.
Typically the tss user and group should be defined at this point, but
this may not always be the case, so make sure that this user and group
are available on the system.

Building things like this in-place is really useful when you can't be
bothered to package and install them for your distribution but still
want to use them. This patch allows building swtpm with libtpms in
place. Simply specify the location to LDFLAGS and CFLAGS on the
configure line
LIBTPMS_CFLAGS=-I/home/jejb/git/libtpms/include/ LIBTPMS_LDFLAGS=-L/home/jejb/git/libtpms/src/.libs/ ./configure
It will then build a version that can run in-place.
I also think it corrects a bug in the original in that if pkg-config
had specified a non standard library location, the version check
wouldn't have used it.
