/*
* `ar' archive handling.
*
* `ar' archives start with signature `ARMAG'. Each archive member is
* preceded by a header containing meta-data for the member. This
* header is described in <ar.h> (struct ar_hdr). The header always
* starts on an even address. File data is padded with "\n"
* characters to keep this invariant.
*
* Special considerations for `ar' archives:
*
* There are two variants of the `ar' archive format: traditional BSD
* and SVR4. These differ in the way long file names are treated, and
* in the layout of the archive symbol table.
*
* The `ar' header only has space for a 16 character file name.
*
* In the SVR4 format, file names are terminated with a '/', so this
* effectively leaves 15 characters for the actual file name. Longer
* file names stored in a separate 'string table' and referenced
* indirectly from the name field. The string table itself appears as
* an archive member with name "// ". An `indirect' file name in an
* `ar' header matches the pattern "/[0-9]*". The digits form a
* decimal number that corresponds to a byte offset into the string
* table where the actual file name of the object starts. Strings in
* the string table are padded to start on even addresses.
*
* In the BSD format, file names can be upto 16 characters. File
* names shorter than 16 characters are padded to 16 characters using
* (ASCII) space characters. File names with embedded spaces and file
* names longer than 16 characters are stored immediately after the
* archive header and the name field set to a special indirect name
* matching the pattern "#1/[0-9]+". The digits form a decimal number
* that corresponds to the actual length of the file name following
* the archive header. The content of the archive member immediately
* follows the file name, and the size field of the archive member
* holds the sum of the sizes of the member and of the appended file
* name.
*
* Archives may also have a symbol table (see ranlib(1)), mapping
* program symbols to object files inside the archive.
*
* In the SVR4 format, a symbol table uses a file name of "/ " in its
* archive header. The symbol table is structured as:
* - a 4-byte count of entries stored as a binary value, MSB first
* - 'n' 4-byte offsets, stored as binary values, MSB first
* - 'n' NUL-terminated strings, for ELF symbol names, stored unpadded.
*
* In the BSD format, the symbol table uses a file name of "__.SYMDEF".
* It is structured as two parts:
* - The first part is an array of "ranlib" structures preceded by
* the size of the array in bytes. Each "ranlib" structure
* describes one symbol. Each structure contains an offset into
* the string table for the symbol name, and a file offset into the
* archive for the member defining the symbol.
* - The second part is a string table containing NUL-terminated
* strings, preceded by the size of the string table in bytes.
*
* If the symbol table and string table are is present in an archive
* they must be the very first objects and in that order.
