* Add function to escape distinguished names
* Test if escaping of trailing space works with multi-byte characters

* Add CLDAP (RFC1798 UDP/Connectionless) support to DialURL

This is actually a deprecated RFC, however Active Directory relies on it
for server discovery.
Without this patch CLDAP is possible via directt use of the the
deprecated `Dial` function with a UDP network connection. This patch
adds the same support to the DialURL function.

* fix: packet referral decoding

This adjusts the packet referral decoding behavior to more appropriately handle edge cases and allows to more easily obtain the underlying packet in the event of a decoding error. Instead of matching ASN.1 BER packets on the tag for referrals we match on the class and type. This is particularly important in regards to OpenLDAP which returns a ASN.1 BER Generalized Time tag for referrals.

* Lint/gofmt fixes.

Lint checks now pass.

* Additional gofmt fix required for go1.19

* implement server side sorting controls (rfc2891)

* implement NewControlServerSideSorting to decode server side sorting request, add server side sorting type to ControlMap

This fixes an issue where attributes with equal chars in the value would not be correctly parsed. As we only set the AttributeTypeAndValue's Type field once and we reset it on the step to the next AttributeTypeAndValue we can assume if this field already has a value that it should not consider it the type/value separator.

Fixes #416

* Add unit test for Close deadlock
* Apply timeout to quit message confirmation
* Avoid panic when Start has not been called
* Add unit test for sendResponse deadlock
* Apply timeout to sending response packet
* Rename test for consistency

This replaces the package-wide logger, used in places like processMessages and reader, and returns instead an error. For backwards compatibility, errors returned from goroutine functions are stored in `Conn.err` and can get retrieved through `Conn.GetLastError`

* add unmarshalling of generalizedTimestamp

this uses the github.com/go-asn1-ber/asn1-ber package to parse the timestamp

* fix: do not overwrite t

* fix: err already declared

* document time.Time is parsed

* adapt error message also

* unmarshal into *DN also

* feat: enable DirSync control in search operation

* fix: fixed ineffectual assignment to err

* fix: fixed should replace loop with error

* fix: not include Cookie in SearchResult struct
