Replaced "" with static const variable A2STR::NIL.
Replaced string comparison against "" with std::string::empty().
Added PROTO_* to Request class and use them as a protocol string
constant.
Made "started", "stopped", "completed" static const variable in
AnnounceList class.
Rewritten SharedHandle. Now copy constructor taking raw pointer
has
keyword explicit and SharedHandle's default constructor
initializes
its internal obj to null, old implementation initializes it
using
obj's default constructor.
To assign null, write SharedHandle<T> x(...); x.reset();
TODO: test/SharedHandleTest.cc needs more tests.
* src/SharedHandle.h
Added XML2SAXMetalinkProcessor class, which is a lot faster than
the predecessor, Xml2MetalinkParser class.
I tested them against 94KB metalink file with 1234 chunk
checksums.
The new one parsed it in 22msec, while it took 6000msec with old
one.
