fd25c0e6dd libcacard: replace qemu thread primitives with glib ones
Replace QemuMutex with GMutex and QemuCond with GCond
(with corresponding function changes), to make libcacard
independent of qemu internal functions.

After this step, none of libcacard internals use any
qemu-provided symbols.  Maybe it's a good idea to
stop including qemu-common.h internally too.

1687a089f1 libcacard: remove useless initializers
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.

fa5912a17b libcacard/vreader: Drop broken recovery from failed assertion
We suppress some code when we got unexpected status and assertion
checking is off:

     assert(card_status == VCARD_DONE);
     if (card_status == VCARD_DONE) {
         int size = MIN(*receive_buf_len, response->b_total_len);
         memcpy(receive_buf, response->b_data, size);
         *receive_buf_len = size;
    }

Such "recovery" is of dubious value even when it works.  This one
doesn't: it fails to assign to receive_buf[] and *receive_buf_len,
which the callers expect.

Make the code unconditional.

78a4b8d205 libcacard: g_malloc cleanups
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.

changes from v24->v25:
 * Fix out of tree builds.
 * Fix build with linux-user targets.

changes from v23->v24: (Jes Sorensen review 2)
 * Makefile.target: use obj-$(CONFIG_*) +=
 * remove unrequired includes, include qemu-common before qemu-thread
  * required adding #define NO_NSPR_10_SUPPORT (harmless)

changes from v22->v23:
 * configure fixes: (reported by Stefan Hajnoczi)
  * test a = b, not a == b (second isn't portable)
  * quote $source_path in case it contains spaces
   - this doesn't really help since there are many other places
     that need similar fixes, not introduced by this patch.

changes from v21->v22:
 * fix configure to not link libcacard if nss not found
    (reported by Stefan Hajnoczi)
 * fix vscclient linkage with simpletrace backend
    (reported by Stefan Hajnoczi)
 * card_7816.c: add missing break in ERROR_DATA_NOT_FOUND
    (reported by William van de Velde)

changes from v20->v21: (Jes Sorensen review)
 * use qemu infrastructure: qemu-thread, qemu-common (qemu_malloc
  and qemu_free), error_report
 * assert instead of ASSERT
 * cosmetic fixes
 * use strpbrk and isspace
 * add --disable-nss --enable-nss here, instead of in the final patch.
 * split vscclient, passthru and docs to following patches.

changes from v19->v20:
 * checkpatch.pl

changes from v15->v16:

Build:
 * don't erase self with distclean
 * fix make clean after make distclean
 * Makefile: make vscclient link quiet

Behavioral:
 * vcard_emul_nss: load coolkey in more situations
 * vscclient:
  * use hton,ntoh
  * send init on connect, only start vevent thread on response
  * read payload after header check, before type switch
  * remove Reconnect
  * update for vscard_common changes, empty Flush implementation

Style/Whitespace:
 * fix wrong variable usage
 * remove unused variable
