 In #33918, we discovered a bug where IPv6 addresses were being truncated
 in logs.

 During the fix, we noticed that we had a TOR_ADDR_BUF_LEN, but no
 equivalent constant for addresses and ports. The new TOR_ADDRPORT_BUF_LEN
 should allow space for:
 * TOR_ADDR_BUF_LEN
 * IPv6 brackets (2, if not included in TOR_ADDR_BUF_LEN already)
 * the port separator (1)
 * the port (5)

 We should check for other truncation errors while making this change.
