Apply clang-format on crypto/* and compat/*
SanitizeString: allow '(' and ')'

'(' and ')' are valid in user agent strings, so should be reported
as such in RPC `getpeerinfo`.

Fixes #4537.
autofile: don't copy CAutoFile by value
autofile: Disallow by-value copies of CAutoFile

One might assume that CAutoFile would be ref-counted so that a copied object
would delay closing the underlying file until all copies have gone out of
scope. Since that's not the case with CAutoFile, explicitly disable copying.
