Merge pull request #2535 from nspcc-dev/drop-hf-prefix

b6829f36fd config: s/HF_Aspidochelone/Aspidochelone/ 
HF_ prefix makes zero sense to me. If it's "hardfork", then it's in the
"Hardforks" section already. If it's "hotfix", then it made some sense back
when it was HF_2712_FixSyscallFees, but now it's codenamed anyway. So we can
drop it and have a cleaner config.

16bf7c1426 core: adjust contract script check on deploy 
Reference implementation doesn't panic if the method offset is out of

and
a65487fa56/src/Neo.VM/Script.cs (L146).

1472c271e6 core: fix native NEO's getCandidateVote signature 
This commit fixes T5 statediff at block #0. Management's storage item
differs between neo-go and C# nodes, the reason in native NEO contract
state.

The parameter should have `pubKey` name, unlike the other `pubkey`
arguments in this contract.

ca127f1615 core: fix native NEO ABI 
This commit fixes T5 statediff at block #0. The reason in Management's
storage state. The diff occurs because of inconsistent NEO methods
order. See
https://github.com/neo-project/neo/issues/2766#issue-1257870089.

The current solution is to preserve C#'s order of methods to be
compatible with current testnet.

9a06995460 bigint: don't allocate in ToPreallocatedBytes 
Turns out, it's almost always allocating because we're mostly dealing with
small integers while the buffer size is calculated in 8-byte chunks here, so
preallocated buffer is always insufficient.

Fix StorageItem reuse at the same time. We don't copy when getting values from
the storage, but we don when we're putting them, so buffer reuse could corrupt
old values.
