This patch addresses three possible buffer overflows in function
unique_service_name(). The three issues have the folowing CVE
numbers:
CVE-2012-5958 Issue #2: Stack buffer overflow of Tempbuf
CVE-2012-5959 Issue #4: Stack buffer overflow of Event->UDN
CVE-2012-5960 Issue #8: Stack buffer overflow of Event->UDN
Notice that the following issues have already been dealt by previous
work:
CVE-2012-5961 Issue #1: Stack buffer overflow of Evt->UDN
CVE-2012-5962 Issue #3: Stack buffer overflow of Evt->DeviceType
CVE-2012-5963 Issue #5: Stack buffer overflow of Event->UDN
CVE-2012-5964 Issue #6: Stack buffer overflow of Event->DeviceType
CVE-2012-5965 Issue #7: Stack buffer overflow of Event->DeviceType
Wrong assignment by shutdown result hides the real error code
of NewRequestHandler() in ssdp_device.c.
Fix return code description of NewRequestHandler().
Handle return code from ithread_create in sample applications.
Remove unused assignments.
In parser_parse_chunky_headers, parser->msg.msg.buf can be changed
by membuffer_delete call. Therefore if we save the pointer to
parser->msg.entity.buf before calling membuffer_delete, it will
induce access to released memory.
Add an additional INET_IPV6 exclusion around IPV6_MULTICAST_HOPS since
the definition isn't guaranteed to exist when the toolchain lacks IPv6
support.

1. Test Instr before dereference it in http_RecvPostMessage.
(Though it never becomes NULL because NULL is not passed to
the static method)
2. Avoid strdup(NULL) in ixmlElement_setAttributeNS.
Those are detected by llvm scan-build.
The variable is declared as SOCKET, but it is used to
store return value of int receive_from_stopSock(...).
The type was changed in the commit
4b47e6a51d9c7049a862695b68de75699e023551 by mistake.
Add --enable-unspecified_server configure option to set to "Unspecified"
the OS name, OS version, product name and product version normally
contained in the SERVER header as this could be used by an attacker.

Miniserver is disabled if ECXLUDE_GENA, EXCLUDE_SOAP and
EXCLUDE_WEBSERVER are set.
However, SSDP needs the Miniserver to answer to M-SEARCH requests.
So, MiniServer should not be disabled if EXCLUDE_SSDP is not also set.
Use INCLUDE_DEVICE_APIS instead of UPNP_HAVE_DEVICE as in other sources.
Don't use soap_device_callback if INCLUDE_DEVICE_APIS is not set,
otherwise link error occur on Windows.

There are typos in upnp/src/inc/config.h "EXCLUDE_SSSDP" (shold be
EXCLUDE_SSDP), therefore EXCLUDE_SSDP is always 0, and --disable-ssdp
has no effect.
Cast parameters of htonl in uint32_t in IN6_IS_ADDR_GLOBAL and
IN6_IS_ADDR_ULA definitions.
Remove comparison with 0 in while statement of vfmatch,
http_SendMessage and http_MakeMessage.
GetDeviceHandleInfo just fail without using undefined member DeviceAf
if UPNP_HAVE_DEVICE is not defined.
Move ContentTypeHeader definition to soap_common.c, since it is
also used in soap_ctrlpt.c.
Comment unused SERVER from DeviceShutdown.
Comment unused max from parse_hostport.
Comment unused nodeptr from ixmlNode_cloneDoc.
Comment unused newNode from Parser_hasDefaultNamespace.
Comment unused Parser_parseReference function
Check return code of shutdown and display an error if needed.

(cherry picked from commit 5969530dcf0c612dd3ba3cd57b5a3d9034f90316)
Modify configure.ac to add --disable-optssdp option. This option will
remove OPT, 01-NLS and X_USER_AGENT headers from SSDP messages as those
headers are optional. If --disable-gena and disable-optssdp are both
used, uuid part will not be compiled anymore.
Change ret_code from int to parse_status_t in match.
Set back return code of ReadResponseLineAndHeaders from parse_status_t
to int as this function can return UPNP_E_BAD_HTTPMSG. As a result, do
not cast the result of this function into parse_status_t in
http_OpenHttpGetProxy and http_OpenHttpGetEx.
Use switch with PARSE_OK in parsetools.c.
Add missing explicit casts of integer constants in uri.c and
httpreadwrite.c.
Use switch, int and sa_family_t with AF_INET in uri.c.
Print an error in http_Download if realloc failed.
Replace if statements with switch when using HND_DEVICE and HND_CLIENT
enum constants.
Correct also UpnpUnRegisterRootDeviceLowPower and UpnpUnRegisterClient
as those functions were wrongly awaiting an UPNP_E_INVALID_HANDLE
instead of HND_INVALID from GetHandleInfo.
Do not compile CreateClientRequestPacketUlaGua if IPv6 is disable.
Cast DestAddr->sa_family from sa_family_t into int when calling
CreateServicePacket as this function has been set back to accept int in
a692e591defe6ed9a617b9b4a083964a01f7bbab.
Use switch instead of if with AF_INET and AF_INET6.
Add missing casts from AF_INET and AF_INET6 into sa_family_t when using
them to set sin_family and sin6_family.
Add missing explicit casts into size_t or lu when using integer
constants with strlen or unsigned long indexes.
Set SSDP_PAUSE to be unsigned as it is used with usleep.
Commit c40d2bc0c9b60c43b641ac4669c7b8bbcd6134c5 has a problem
at removing the parentheses in parser_parse_responseline.
Difference of pointers was used with intention, don't cast
them separately.
Previous change broke the feature. The error of unique_service_name
in ssdp_request_type should be ignored.
This reverts commit 5944960e172a797a9fcc196291f4046cafa7f6ec.

There was a problem in HDR_ACCEPT_LANGUAGE case.
It may read from TmpBuf larger amount than allocated,
since condition was always true.
Terminate RespInstr->AcceptLanguageHeader correctly.
Skip allocation if there is already sufficient buffer.
