* common/sysutils.c (gnupg_reopen_std): Use fcntl instead of fstat.
--
When gpg was invoked by a Perl web application on FreeBSD, fstat in
gnupg_reopen_std failed with EBADF. Using fcntl, which is considered
lighter than fstat, it works fine. Since uur purpose is to check if
file descriptor is valid or not, lighter operation is better.

This actually fixes a couple of cases for Windows. Both --home-dir

correct one but because we need an absolute dir anyway it is the less
surprising one. Note that this does not include a full syntax check
and fixup and thus it is very well possible that the result is not an
absolute directory.

--
This fixes a potential overflow if LFs are passed to the status
string functions. This is actually not the case and would be wrong
because neither the truncating in libassuan or our escaping is not the
Right Thing. In any case the functions need to be more robust and
comply to the promised interface. Thus the code has been factored out
to a helper function and N has been bumped up correctly and checked in
all cases.
For some uses this changes the behaviour in the error case (i.e. CR or
LF passed): It will now always be C-escaped and not passed to
libassuan which would truncate the line at the first LF.

I did some test to see whether this has an effect. A test program

compression. Single read means the old behaviour, multi read the new
behaviour which fills up the buffer when the read(2) returned only 4k
in once call.

--
Originally the KBX code was written to allow standalone use. However
this required lot of ugliness like separate memory allocators and
such. It also precludes the use of some standard functions from
common due to their use of the common gnupg malloc functions.
Dropping all that makes things easier. Minor disadvantages: the kbx
call done for gpg will now use gcry malloc fucntions and not the
standard malloc functions. This might be a bit slower but removing
them even fixes a possible bug in keybox_tmp_names which is used in
gpg and uses gpg's xfree which is actually gcry_free.

* common/logging.h [GPGRT_LOG_WITH_PREFIX]: Do not define the log

logging.h uses constants we plan to use for future versions of

thus I run into a conflict. This patch protects against this and make

It was not the best idea to use constants from a planned libgpg-error
in the first place. The actual problem are the enums, the macros
won't harm.

This patch enables the use of the log function from libgpgrt (aka
libgpg-error). Instead of checking a version number, we enable them
depending on macros set by recent gpg-error versions. Eventually the
whole divert stuff can be removed.
The -Wno-format-zero-length is required because log_printhex can be
called with an empty format string. Note that this is fully specified
standard C behaviour.
