David Vossel d16b89be17 RFC compliant uri and display-name encode/decode ... 1. URI Encoding This patch changes ast_uri_encode()'s behavior when doreserved is enabled. Previously when doreserved was enabled only a small set of reserved characters were encoded. This set was comprised primarily of the reserved characters defined in RFC3261 section 25.1, but contained other characters as well. Rather than only escaping the reserved set, doreserved now escapes all characters not within the unreserved set as defined by RFC 3261 and RFC 2396. Also, the 'doreserved' variable has been renamed to 'do_special_char' in attempts to avoid confusion. When doreserve is not enabled, the previous logic of only encoding the characters <= 0X1F and > 0X7f remains, except for the '%' character, which must always be encoded as it signifies a HEX escaped character during the decode process. 2. URI Decoding: Break up URI before decode. In chan_sip.c ast_uri_decode is called on the entire URI instead of it's individual parts after it is parsed. This is not good as ast_uri_decode can introduce special characters back into the URI which can mess up parsing. This patch resolves this by not decoding a URI until parsing is completely done. There are many instances where we check to see if pedantic checking is enabled before we decode a URI. In these cases a new macro, SIP_PEDANTIC_DECODE, is used on the individual parsed segments of the URI rather than constantly putting if (pedantic) { decode() } checks everywhere in the code. In the areas where ast_uri_decode is not dependent upon pedantic checking this macro is not used, but decoding is still moved to each individual part of the URI. The only behavior that should change from this patch is the time at which decoding occurs. Since I had to look over every place URI parsing occurs to create this patch, I found several places where we use duplicate code for parsing. To consolidate the code, those areas have updated to use the parse_uri() function where possible. 3. SIP display-name decoding according to RFC3261 section 25. To properly decode the display-name portion of a FROM header, chan_sip's get_calleridname() function required a complete re-write. More information about this change can be found in the comments at the beginning of this function. 4. Unit Tests. Unit tests for ast_uri_encode, ast_uri_decode, and get_calleridname() have been written. This involved the addition of the test_utils.c file for testing the utils api.
