With TYPEDEF_HIDES_STRUCT set, Doxygen properly handles anonymous
structs and enums that are typedef'd. file: [d50442556a] check-in: [2fcf5a3052] user: js, branch: trunk, size: 8234 [annotate] [blame] [check-ins using] [diff]

This is a new superclass for OFTCPSocket to allow sharing code with
other IP stream socket types, namely SCTP. file: [311250de1e] check-in: [3dfe642dd3] user: js, branch: trunk, size: 8338 [annotate] [blame] [check-ins using] [diff]

These are different enough that it makes no sense to have them in one.
Having them in one means all methods are @optional and typos cannot be
caught by the compiler. file: [e885685095] check-in: [e3c911c7f5] user: js, branch: trunk, size: 8215 [annotate] [blame] [check-ins using] [diff]

This temporarily doesn't use the search domains anymore and makes CNAMEs
slightly more inefficient. The next commits will fix both. file: [9a991f874e] check-in: [ee592cf603] user: js, branch: trunk, size: 8003 [annotate] [blame] [check-ins using] [diff]

This is now in alignment with the terminology of the RFC. file: [3539989488] check-in: [d69f7bc1ff] user: js, branch: trunk, size: 8194 [annotate] [blame] [check-ins using] [diff]

This makes it easier to attach them to a query. file: [5daf5f77ab] check-in: [4fd5a7086c] user: js, branch: trunk, size: 8220 [annotate] [blame] [check-ins using] [diff]

This allows ABI stability with the fragile ABI. file: [7a80eed2c3] check-in: [496695d778] user: js, branch: trunk, size: 9732 [annotate] [blame] [check-ins using] [diff]

Because there is usually only one resolver per thread, having the
delegate as a property on the resolver would not work. It is therefore
passed as an argument.

This only changes the public API so far. Internally, the old target /
selector / context pattern is still being used. This will be changed
later. file: [83d8704f5a] check-in: [0afb04d93c] user: js, branch: trunk, size: 9700 [annotate] [blame] [check-ins using] [diff]

This provides more convenience when the goal is to connect a socket and
provides functionality similar to getaddrinfo().

No support for resolving CNAMEs yet - this will be the next step. file: [6f6cb9c138] check-in: [8555d64ee6] user: js, branch: trunk, size: 10230 [annotate] [blame] [check-ins using] [diff]

This does nothing more than parse /etc/hosts and /etc/resolv.conf so
far. file: [99b6530961] check-in: [dd375b6d4e] user: js, branch: trunk, size: 2317 [annotate] [blame] [check-ins using]
