Update DB\IO with auto query placeholder rewrite and better error logging

Browse Source 
All errors have context that is used to add query, params, etc info
for logging into the DB.
Avoid double logging for PostGreSQL direct errors as those will be
logged now in context to the actual error log
Remove error: 16 missing/empty dbh has this is handled with error 14
in the connect method.

Auto convert ?, :named to $numbered, default off. Activate with
'db_convert_placeholder' flag or method dbSetConvertPlaceholder.
Converted result data for single queries in dbGetPlaceholderConverted
or in the cursor_ext array in placeholer_converted key

Do not auto translate debug queries with placeholder values in query
but keep them in the array in the context array. If needed
'db_debug_replace_placeholder' can be set to show prepared query
with placeholder replaced in the context

New methods:
public function dbSetConvertPlaceholder(bool $flag): void
public function dbGetConvertPlaceholder(): bool
public function dbSetConvertPlaceholderTarget(string $target): bool
public function dbGetConvertPlaceholderTarget(): string
public function dbSetDebugReplacePlaceholder(bool $flag): void
public function dbGetDebugReplacePlaceholder(): bool
public function dbGetPlaceholderConverted(): array

Chagned to public:
public function dbCheckQueryForSelect(string $query): bool
public function dbCheckQueryForInsert(string $query, bool $pure = false): bool
public function dbCheckQueryForUpdate(string $query): bool
