50fd77045e2f858a53486b5e02e1798c92ab946c [init] Read/decode asmap before constructing addrman (John Newbery)
Pull request description:
Commit 181a1207 introduced an initialization order bug: CAddrMan's m_asmap must be set before deserializing peers.dat.
The first commit restores the correct initialization order. The remaining commits make `CAddrMan::m_asmap` usage safer:
- don't reach into `CAddrMan`'s internal data from `CConnMan`
- set `m_asmap` in the initializer list and make it const
- make `m_asmap` private, and access it (as a reference to const) from a getter.
This ensures that peers.dat deserialization must happen after setting m_asmap, since m_asmap is set during CAddrMan construction.
