* The error code packs differently depending on if it records a system

* A system error packs like this (we follow POSIX and only allow positive
* numbers that fit in an |int|):
*
* +-+-------------------------------------------------------------+
* |1| system error number |
* +-+-------------------------------------------------------------+
*
* An OpenSSL error packs like this:
*
* <---------------------------- 32 bits -------------------------->
* <--- 8 bits ---><------------------ 23 bits ----------------->
* +-+---------------+---------------------------------------------+
* |0| library | reason |
* +-+---------------+---------------------------------------------+
*
* A few of the reason bits are reserved as flags with special meaning:
*
* <4 bits><-------------- 19 bits ------------->
* +-------+-------------------------------------+
* | rflags| reason |
* +-------+-------------------------------------+
*
* We have the reason flags being part of the overall reason code for
* backward compatibility reasons, i.e. how ERR_R_FATAL was implemented.
