* common/homedir.c (_gnupg_socketdir_internal): Fix error handling.
--
Prior to 26086b36 the non-existance of the socket directory was
considered an error if a non-default home directory is used. Since
26086b36 we now create the directory on demand, but the function still
returned the fallback path. This made the agent bind the socket in
the socket directory, and the client trying to connect to the socket
in the home directory.

(is_file_compressed): Rerad 2 more bytes and call new function.
--
Note that this does not yet allow to detect compressed data piped to
gpg. This requires a proper read-ahead in iobuf.c which is
complicated due to the auto-removal of filter functions. Thus such an
read-ahead needs to be done in the I/O backend of iobuf.

Although there is no auto cleanup (yet) this should be helpful. Let's

Our regression test suite makes use of the envvar GNUPG_BUILDDIR. Now
the code in gnupg for evaluating this envvar is only included in a
development version (that is one with a "-betaNNN" suffix). For a
real release the envvar is not considered. However during a "make
distcheck" a "make check" is done for the build directory. Without
defining that envar we would try to run binaries in the install
directory ("_inst" sub-directory) which are not yet installed at that
time.

This addresses two bugs:
- Using the "-&@INEXTRA@" kludges requires that we pass the value of
the handle on the command line and not the libc fd.
- gpgrt_poll requires the use of the ReadFile/WriteFile backend which
is currently only used when the stream has been created with
gpgrt_sysopen.

Consider a situation where the user passes "--status-fd 3" but file
descriptor 3 is not open.
During the course of executing the rest of the commands, it's possible
that gpg itself will open some files, and file descriptor 3 will get
allocated.
In this situation, the status information will be appended directly to
whatever file happens to have landed on fd 3 (the trustdb? the
keyring?).
This is a potential data destruction issue for all writable file
descriptor options:
--status-fd
--attribute-fd
--logger-fd
It's also a potential issue for readable file descriptor options, but
the risk is merely weird behavior, and not data corruption:
--override-session-key-fd
--passphrase-fd
--command-fd
Fixes this by checking whether the fd is valid early on before using
it.
