snmp: Patch 1118
OTP-8574 The SMI specifies that an table row OID should be named: { "1" }. An option has been introduced, relaxed_row_name_assign_check, that allows for a more liberal numbering scheme. OTP-8594 Changes to make snmp (forward) compatible with the new version of the crypto application (released in R14). As of R14, crypto is implemented using NIFs. Also, the API is more strict. OTP-8648 [manager] Changed default value for the MIB server cache. Auto GC is now on by default. OTP-8563 Decoding of Counter64 values larger then 9306882749598007295 fails. Counter64 is encoded as an 64 bit signed integer, but is actually an unsigned integer, which the decoder does not take into account. OTP-8595 [compiler] Fails to compile non-contiguous BITS. Per Hedeland OTP-8646 [manager] Raise condition causing the manager server process to crash. Unregistering an agent while traffic (set/get-operations) is ongoing could cause a crash in the manager server process (raise condition).
