/* Attribute access routines are all defined by the following parameters.
*
* sdp_ptr The SDP handle returned by sdp_init_description.
* level The level the attribute is defined. Can be either
* SDP_SESSION_LEVEL or 0-n specifying a media line level.
* inst_num The instance number of the attribute. Multiple instances
* of a particular attribute may exist at each level and so
* the inst_num determines the particular attribute at that
* level that should be accessed. Note that this is the
* instance number of the specified type of attribute, not the
* overall attribute number at the level. Also note that the
* instance number is 1-based. For example:
* v=0
* o=mhandley 2890844526 2890842807 IN IP4 126.16.64.4
* s=SDP Seminar
* c=IN IP4 10.1.0.2
* t=0 0
* m=audio 1234 RTP/AVP 0 101 102
* a=foo 1
* a=foo 2
* a=bar 1 # This is instance 1 of attribute bar.
* a=foo 3 # This is instance 3 of attribute foo.
* cap_num Almost all of the attributes may be defined as X-cpar
* parameters (with the exception of X-sqn, X-cap, and X-cpar).
* If the cap_num is set to zero, then the attribute is not
* an X-cpar parameter attribute. If the cap_num is any other
* value, it specifies the capability number that the X-cpar
* attribute is specified for.

/* Attribute handling:
*
* There are two basic types of attributes handled by the SDP library,
* those defined by a= token lines, and those embedded with a=X-cpar lines.
* The handling for each of these is described here.
*
* Simple (non X-cpar attributes):
*
* Attributes not embedded in a=X-cpar lines are referenced by level and
* instance number. For these attributes the capability number is always
* set to zero.
*
* An application will typically process these attributes in one of two ways.
* With the first method, the application can determine the total number
* of attributes defined at a given level and process them one at a time.
* For each attribute, the application will query the library to find out
* what type of attribute it is and which instance within that type. The
* application can then process this particular attribute referencing it
* by level and instance number.
*
* A second method of processing attributes is for applications to determine
* each type of attribute they are interested in, query the SDP library to
* find out how many of that type of attribute exist at a given level, and
* process each one at a time.
*
* X-cpar attribute processing:
*
* X-cpar attributes can contain embedded attributes. They are associated
* with X-cap attribute lines. An example of X-cap and X-cpar attributes
* found in an SDP is as follows:
*
* v=0
* o=- 25678 753849 IN IP4 128.96.41.1
* s=-
* t=0 0
* c=IN IP4 10.1.0.2
* m=audio 3456 RTP/AVP 18 96
* a=rtpmap:96 telephone-event/8000
* a=fmtp:96 0-15,32-35
* a=X-sqn: 0
* a=X-cap: 1 audio RTP/AVP 0 18 96 97
* a=X-cpar: a=fmtp:96 0-16,32-35
* a=X-cpar: a=rtpmap:97 X-NSE/8000
* a=X-cpar: a=fmtp:97 195-197
* a=X-cap: 5 image udptl t38
* a=X-cap: 6 application udp X-tmr
* a=X-cap: 7 audio RTP/AVP 100 101
* a=X-cpar: a=rtpmap:100 g.711/8000
* a=X-cpar: a=rtpmap:101 g.729/8000
*
* X-cap attributes can be defined at the SESSION_LEVEL or any media level.
* An X-cap attr is defined by the level and instance number just like
* other attributes. In the example above, X-cap attrs are defined at
* media level 1 and there are four instances at that level.
*
* The X-cpar attributes can also be referenced by level and instance number.
* However, the embedded attribute within an X-cpar attribute must be
* referenced by level, instance number, and capability number. This is
* because the X-cpar attribute is associated with a particular X-cap/
* capability.
* For all attributes that are not embedded within an X-cpar attribute, the
* cap_num should be referenced as zero. But for X-cpar attributes, the
* cap_num is specified to be one of the capability numbers of the previous
* X-cap line. The number of capabilities specified in an X-cap line is
* equal to the number of payloads. Thus, in this example, the first X-cap
* attr instance specifies capabilities 1-4, the second specifies capability
* 5, the third capability 6, and the fourth capabilities 7-8.
*
* X-cpar attributes can be processed with methods similar to the two
* previously mentioned. For each X-cap attribute, the application can
* use one of two methods to process the X-cpar attributes. First, it
* can query the total number of X-cpar attributes associated with a
* given X-cap attribute. The X-cap attribute is here defined by a level
* and a capability number. In the example above, the total number of
* attributes defined is as follows:
* level 1, cap_num 1 - total attrs: 3
* level 1, cap_num 5 - total attrs: 0
* level 1, cap_num 6 - total attrs: 0
* level 1, cap_num 7 - total attrs: 2
*
* Note that if the application queried the number of attributes for
* cap_num 2, 3, or 4, it would also return 3 attrs, and for cap_num
* 8 the library would return 2.
*
* Once the application determines the total number of attributes for
* that capability, it can again query the embedded attribute type and
* instance. For example, sdp_get_attr_type would return the following:
* level 1, cap_num 1, attr 1 -> attr type fmtp, instance 1
* level 1, cap_num 1, attr 2 -> attr type rtpmap, instance 1
* level 1, cap_num 1, attr 3 -> attr type fmtp, instance 2
* level 1, cap_num 7, attr 1 -> attr type rtpmap, instance 1
* level 1, cap_num 7, attr 2 -> attr type rtpmap, instance 2
*
* The individual embedded attributes can then be accessed by level,
* cap_num, and instance number.
*
* With the second method for handling X-cpar attributes, the application
* determines the types of attributes it is interested in. It can then
* query the SDP library to determine the number of attributes of that
* type found for that level and cap_num, and then process each one at
* a time. e.g., calling sdp_attr_num_instances would give:
* level 1, cap_num 1, attr_type fmtp -> two instances
* level 1, cap_num 1, attr_type rtpmap -> one instance
* level 1, cap_num 7, attr_type fmtp -> zero instances
* level 1, cap_num 7, attr_type rtpmap -> two instances

/* Function: sdp_copy_attr
* Description: Copy an attribute from one SDP/level to another. A new

* list at the dst SDP/level and all parameter values are
* copied.
* Description: Add a new attribute of the specified type at the given
* level and capability level or base attribute if cap_num
* is zero.
* Parameters: src_sdp_ptr The source SDP handle.
* dst_sdp_ptr The dest SDP handle.
* src_level The level of the source attribute.
* dst_level The level of the source attribute.
* src_cap_num The src capability number associated with the
* attribute if any.
* dst_cap_num The dst capability number associated with the
* attribute if any. Note that src and dst
* cap_num must both be zero or both be non-zero.
* src_attr_type The type of source attribute. This cannot
* be SDP_ATTR_X_CAP or SDP_ATTR_X_CPAR.
* src_inst_num The instance number of the source attr.
* Returns: SDP_SUCCESS Attribute was successfully copied.
