/*
* Member handling
* Archive members have an ASCII header. A Member structure
* holds internal information. Because the ASCII file header
* may be clobbered, Member holds a private, safe copy.
* The ar_name member of m_hdr points at m_name except for string
* table names. Ar_rawname in m_hdr always points at m_raw.
*
* m_raw The original ar_name with null termination.
* E.g., "name/ "
*
* m_name The processed name, with '/' terminator changed to '\0'.
* Unused for string table names. E.g., "name\0 "
*
* To improve performance of member lookup we allocate lists which
* contain MEMIDENTNO members:
*
* ed_memlist --> ---------------------
* | m_next |
* | m_end |
* | m_free |
* |---------------------|
* | m_offset | m_member |
* | m_offset | m_member |
* | " | " |
* ---------------------
