/*-
 * The error code packs differently depending on if it records a system
 * error or an OpenSSL error.
 *
 * 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:
 *
 *                    <5 bits-<>--------- 19 bits ----------------->
 *                   +-------+-+-----------------------------------+
 *                   | rflags| |          reason                   |
 *                   +-------+-+-----------------------------------+
 *                            ^
 *                            |
 *                           ERR_RFLAG_FATAL = ERR_R_FATAL
 *
 * The reason flags are part of the overall reason code for practical
 * reasons, as they provide an easy way to place different types of
 * reason codes in different numeric ranges.
 *
 * The currently known reason flags are:
 *
 * ERR_RFLAG_FATAL      Flags that the reason code is considered fatal.
 *                      For backward compatibility reasons, this flag
 *                      is also the code for ERR_R_FATAL (that reason
 *                      code served the dual purpose of flag and reason
 *                      code in one in pre-3.0 OpenSSL).
 * ERR_RFLAG_COMMON     Flags that the reason code is common to all
 *                      libraries.  All ERR_R_ macros must use this flag,
 *                      and no other _R_ macro is allowed to use it.
