Calling truncate on /dev/null can happen by the download methods if they
are instructed to download a file to /dev/null (as testcases are only
interested in the status code, but do not support HEAD requests yet)
So just ignore truncate calls on the /dev/null file as it is always
empty anyway, so truncating to zero isn't a problem.

FileFd currently supports no fileflags which would make sense to provide
via mkostemp, so we can just use mkstemp here which is a standard
function compared to glib extension mkostemp.
O_CREAT (Create) and O_TRUNC (Empty) are implied by O_EXCL, which is the
mode mkstemp uses by default. The file description is opened ReadWrite,
but that used to be the default for FileFd in the old times and not a
problem as the difference is needed by FileFd to decide in which way the
compressor pipeline needs to be created (if any).

Avoid the warning "the use of `mktemp' is dangerous,
better use `mkstemp' or `mkdtemp'". It is not strictly necessary to
change the usage from a security point of view here, but mktemp is
also removed from the standard since POSIX.1-2008.
The mkostemp call returns a file descriptor the logic for
TemporaryFileName has been changed accordingly to get the same results.
The file permissions are corrected by using fchmod() as the default for
FileFd is 666 while mkstemp creates files with 600 by default.

The fix avoid the warning "comparison between signed and
unsigned integer expressions [-Wsign-compare]"· The index for the loop needs
to be unsigned for compare with globbuf.gl_pathc structure

GCC 4.8 is now clever enough to warn about:
contrib/sha2_internal.cc: In function ‘char* SHA256_End(SHA256_CTX*, char*)’:
contrib/sha2_internal.cc:656:31: warning: argument to ‘sizeof’ in ‘void*
memset(void*, int, size_t)’ call is the same expression as the destination;
did you mean to dereference it? [-Wsizeof-pointer-memaccess]
MEMSET_BZERO(context, sizeof(context));
So fix it as suggested. Its interesting though that the SHA2*
calculation as far as we need it works even without zeroing out.

With the selfgrown splitting we got the problem of not recovering
from networks which just reply with invalid data like those sending
us login pages to authenticate with the network (e.g. hotels) back.
The good thing about the InRelease file is that we know that it must
be clearsigned (a Release file might or might not have a detached sig)
so if we get a file but are unable to split it something is seriously
wrong, so there is not much point in trying further.
The Acquire system already looks out for a NODATA error from gpgv,
so this adds a new error message sent to the acquire system in case
the splitting we do now ourselves failed including this magic word.
Closes: #712486

Testing for global PendingErrors in users of CopyFile is incorrect
in so far as unrelated errors will prevent us from copying perfectly
fine files and checking for the validity of the files is just better
in CopyFiles as it already checks if files are at least opened.
Add also a higher-level error message to the error stack if it fails.

OpenInternDescriptor failures would cause additional errors to be
generated by double-closing an fd. Other errors (although these
are generated if the method is used incorrectly, so unlikely)
didn't close the fd aswell.
Closes: 704608

Previously some errors would set the Fail flag while some didn't
without a clear reason as all errors leave a bad FileFd behind,
so we use a helper now to ensure that all errors set the flag.

free to escape all lines (we have no lines in our files which need
to be escaped as these would be invalid fieldnames) and while ExecGPGV
would detect dash-escaped text as invalid (as its not expected in
messages with detached signatures) it would be possible to "comment"
lines in (signed) dsc files which are only parsed but not verified

apt-pkg/deb/deblistparser.cc:
- use OpenMaybeClearSignedFile to be free from detecting and
skipping clearsigning metadata in dsc and Release files
We can't write a "clean" file to disk as not all acquire methods copy
Release files before checking them (e.g. cdrom), so this reverts recombining,
but uses the method we use for dsc files also in the two places we
deal with Release files
