CCoinsKeyHasher::operator() should return size_t

It currently returns uint64_t, which on older boost (at least 1.46) causes
test failures on 32-bit systems.

This problem was introduced in bc42503.

Fixes #4634.
Added bullet point

To make it easier to add new requirements if necessary
Merge pull request #4635

[Qt] Add TRY_LOCK back to peertablemodel
Reduce maximum coinscache size during verification

Due to growing coinsviewcaches, the memory usage with checklevel=3
(and standard settings for dbcache) could be up to 500MiB on a
64-bit system. This is about twice the peak during reindexing,
unnecessarily extending bitcoind's memory envelope.

This commit reduces the maximum total size of the caches used during
verification to just nCoinCacheSize, which should be the limit.
