00468b4650 Add TLS client events, server probing, and srv cert matching
This allows external programs (e.g., UI) to get more information
about server certificate chain used during TLS handshake. This can
be used both to automatically probe the authentication server to
figure out most likely network configuration and to get information
about reasons for failed authentications.

The follow new control interface events are used for this:
CTRL-EVENT-EAP-PEER-CERT
CTRL-EVENT-EAP-TLS-CERT-ERROR

In addition, there is now an option for matching the server certificate
instead of the full certificate chain for cases where a trusted CA is
not configured or even known. This can be used, e.g., by first probing
the network and learning the server certificate hash based on the new
events and then adding a network configuration with the server
certificate hash after user have accepted it. Future connections will
then be allowed as long as the same server certificate is used.

Authentication server probing can be done, e.g., with following
configuration options:
    eap=TTLS PEAP TLS
    identity=""
    ca_cert="probe://"

Example set of control events for this:
CTRL-EVENT-EAP-STARTED EAP authentication started
CTRL-EVENT-EAP-PROPOSED-METHOD vendor=0 method=21
CTRL-EVENT-EAP-METHOD EAP vendor 0 method 21 (TTLS) selected
CTRL-EVENT-EAP-PEER-CERT depth=0 subject='/C=US/ST=California/L=San Francisco/CN=Server/emailAddress=server@kir.nu' hash=5a1bc1296205e6fdbe3979728efe3920798885c1c4590b5f90f43222d239ca6a
CTRL-EVENT-EAP-TLS-CERT-ERROR reason=8 depth=0 subject='/C=US/ST=California/L=San Francisco/CN=Server/emailAddress=server@kir.nu' err='Server certificate chain probe'
CTRL-EVENT-EAP-FAILURE EAP authentication failed

Server certificate matching is configured with ca_cert, e.g.:
    ca_cert="hash://server/sha256/5a1bc1296205e6fdbe3979728efe3920798885c1c4590b5f90f43222d239ca6a"

This functionality is currently available only with OpenSSL. Other
TLS libraries (including internal implementation) may be added in
the future.

d1f9c410c1 Remove src/drivers/scan_helpers.c
Most of this file was already moved into wpa_supplicant/scan.c and
we can remove the file completely by having couple of small helper
functions copied to the remaining users outside core wpa_supplicant
code.

ce4f7fdbdd dbus: Get rid of libxml2 dependency with introspection
The XML used in D-Bus introspection is simple and there is no need to use
libxml2 to generate it. This gets rid of the dependency on the large
library by using internal XML generation.

8ddef94bd4 dbus: Share common initialization code for both old and new interface
This was mostly identical code that had been copied for the new D-Bus
API implementation and as such, should really have been shared from
the beginning. In addition, the copied code ended up generating
interesting stack traces since the actual D-Bus connection was being
shared even though the pointer to it was stored in two distinct
data structures. The old D-Bus code ended up dispatching some
D-Bus callbacks which ended up running the new D-Bus code.

Since the private context pointers were mostly identical, everything
seemed to more or less work, but this design was just making things
more complex and potentially very easy to break.

34359a3fb1 Include BSS table unconditionally in the wpa_supplicant build
This will allow more cleanup to be done for scan results processing
since all code can now be made to depend on the BSS table instead of
the temporary scan results.

Once remaining code has been converted to use the BSS table, the new
scan results can be freed immediately after the BSS table has been
updated. In addition, filtering of BSS information should be added
to better support systems with limited resources. For now, memory
use can be limited by defining WPA_BSS_MAX_COUNT to be smaller.
Anyway, better filtering of results to only the configured networks
should be added to improve this.

83922c2d34 Add BSS table to track scan results without dropping information
Collect information from scan results into a BSS table that will not
expire information as quickly as scan results where every new scan,
no matter for how limited set of channels/SSIDs, clears all old
information.

For now, this is only used for D-Bus BSS added/removed notifications,
but this will likely be extended to be used internally instead of the
scan results to better support partial scans.

1057d78eb8 Move generic AP functionality implementation into src/ap
This code can be shared by both hostapd and wpa_supplicant and this
is an initial step in getting the generic code moved to be under the
src directories. Couple of generic files still remain under the
hostapd directory due to direct dependencies to files there. Once the
dependencies have been removed, they will also be moved to the src/ap
directory to allow wpa_supplicant to be built without requiring anything
from the hostapd directory.

a206a29a54 dbus: Remove the confusing "ctrl_iface_" prefix from file names
The D-Bus interface does not really have anything to do with the
wpa_supplicant ctrl_iface interface and as such, this prefix in
dbus files is both confusing and unnecessarily. Make the file names
shorter by removing this prefix.

fb4baa688b Add memory allocation analyzer to verify OS wrapper use
WPA_TRACE=y builds will now verify that memory allocation in done
consistently using os_{zalloc,malloc,realloc,strdup,free} (i.e., no
mixing of os_* functions and unwrapper functions). In addition, some
common memory allocation issues (double-free, memory leaks, etc.) are
detected automatically.

resources are not released correctly. In addition, this will print out
a backtrace automatically if SIGSEGV is received.

7e683ceeb4 WPS: Handle Selected Registrar as a union of info from all Registrars
Instead of using the latest selected registrar change, collect selected
registrar information separately from all registrars and use the union
of this information when building the WPS IE for Beacon and Probe
Response frames.

Note: SetSelectedRegistrar UPnP action does not include a unique
identifier, so the ER matching routine is based only on the IP address
of the ER. In theory, there could be multiple ERs using the same IP
address (but different port or URL), so there may be some corner cases
that would not always match the correct ER entry at the AP. Anyway, this
is not really expected to occur in normal use cases and even if it did
happen, the selected registrar information is not any worse than it was
before when only the last change from any registrar for being
advertized.

8fc2fb56e4 wpa_supplicant: new DBus API implementation
This patch implements the new DBus API. Both, the new and the
previous API may work concurrently and may be turned on or off
separately in .config file.
Some features of the new API are:
 - more wpa_supplicant's events are signaled with DBus signals,
 - introspection data (requires libxml2 and may be disabled),
 - CurrentBSS and CurrentNetwork properties,
 - PropertyChanged signal for most of properties,
 - Relatively easy to extend.
.config options for the new API are: CONFIG_CTRL_IFACE_DBUS_NEW=y and
CONFIG_CTRL_IFACE_DBUS_INTRO=y for introspection.

This commit misses couple of parts from the full implementation
(these are still under review):
- fetching all configuration parameters for learning WPS information
- scan result BSS add/remove notification (register_bss() and
  unregister_bss() notification callbacks)
