vcard_emul_reset currently only logs NSS out, but there is a TODO
for potentially sending insertion/removal events when powering down
or powering up.
For clarity, this commit moves the current guts of vcard_emul_reset to
a new vcard_emul_logout function which will never send insertion/removal
events. The vcard_emul_reset function now just calls vcard_emul_logout,
but also retains its TODO for watching power state transitions and sending
insertion/removal events.

libcacard has many functions which initializes local variables
at declaration time, which are always assigned some values later
(often right after declaration). Clean up these initializers.

The currrent code in libcacard/vcard_emul_nss.c:vcard_emul_options()
has a weird bug in variable usage around expanding opts->vreader
array.
There's a helper variable, vreaderOpt, which is first needlessly
initialized to NULL, next, conditionally, only we have to expand
opts->vreader, receives array expansion from g_renew(), and next,
even if we don't actually perform expansion, the value of this
variable is assigned to the actual array, opts->vreader, which
was supposed to be expanded.
So, since we expand the array by READER_STEP increments, only
once in READER_STEP (=4) the code will work, in other 3/4 times
it will fail badly.
Fix this by not using this temp variable when expanding the
array, and by dropping the useless =NULL initializer too -
if it wasn't in place initially, compiler would have warned
us about this problem at the beginning.

Bailing out when PK11_FindGenericObjects() returns null ensures the
loop that follows it executes at least once. The "loop did not
execute" test right after it is useless. Drop it.

This patch replaces g_malloc() in libcacard into g_new()
or g_new0() where appropriate (removing some init-to-zero
surrounding code), g_malloc+memcpy into g_memdup() and the
like.

Commit 2e679780ae86c6ca8 replaced strncpy() with pstrcpy()
in one place in libcacard. This is a qemu-specific function,
while libcacard is a stand-alone library (or tries to be).
But since we know the exact length of the string to copy,
and know that it definitely will fit in the destination
buffer, use memcpy() instead, and null-terminate the string
after that.
An alternative is to use g_strlcpy() or strncpy(), but memcpy()
is more than adequate in this place.

The local function vcard_emul_alloc_arrays always returned PR_TRUE.
Therefore cppcheck complained about code which handled the
non-existent PR_FALSE case.

Older coolkey versions (before the future fix of RHBZ 802435) have
a fake card reader created if no reader is detected during module
initialization. Warn libcacard users if the faulty coolkey is detected
by checking for the fake reader name "E-Gate 0 0".

When starting with no readers, coolkey should show no slots (with
RHBZ 806038 fixed). Fix initialization to launch the event handling
thread for each module that isn't the internal module regardless of the
number of slots detected for it at initialization time, since slot
number may start as 0 and is dynamic.

The previous parser had copy and paste errors when computing
vname_length and type_params_length, "name" was used instead
of respectively vname and type_params. This led to length that could
be bigger than the input string, and to access out of the array
bounds when trying to copy these strings. valgrind rightfully
complained about this. It also didn't handle empty fields correctly,

vcard_emul_options used args = strip(args++) a few times, which
was not returning the expected result since the rest of the code
expected args to be increased by at least 1, which is not the case
if *args is not a blank space when this function is called.
Replace these calls by "strip(args+1)" which will do what we expect.

vcard_emul_mirror_card and vcard_emul_init use
vcard_emul_alloc_arrays to allocate memory for temporary arrays
which will contain elements that in the end will be used one by
one in cac_card_init. The arrays themselves are never stored
anywhere, they are only used as temporary containers. Hence
the memory that was allocated for these arrays should be freed
after use or they will be leaked.
