p2p: declare Announcement::m_state as uint8_t, add getter/setter

to silence these Travis CI GCC compiler warnings:

txrequest.cpp:73:21: warning: ‘{anonymous}::Announcement::m_state’ is
too small to hold all values of ‘enum class {anonymous}::State’
     State m_state : 3;
                     ^
The warnings are based on the maximum value held by the underlying uint8_t
enumerator type, though the intention of the bitfield declaration is the
maximum declared enumerator value.

The warning been silenced in GCC 8.4+ and 9.3+ according to
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=61414
