Michael Brown 3c68ff99ea [tables] Incorporate table data type information into table definition
Eliminate the potential for mismatches between table names and the
table entry data type by incorporating the data type into the
definition of the table, rather than specifying it explicitly in each
table accessor method.

Michael Brown 1266d7902b [tables] Redefine methods for accessing linker tables
Intel's C compiler (icc) chokes on the zero-length arrays that we
currently use as part of the mechanism for accessing linker table
entries.  Abstract away the zero-length arrays, to make a port to icc
easier.

Introduce macros such as for_each_table_entry() to simplify the common
case of iterating over all entries in a linker table.

Represent table names as #defined string constants rather than
unquoted literals; this avoids visual confusion between table names
and C variable or type names, and also allows us to force a
compilation error in the event of incorrect table names.

Michael Brown f6a8158eed Make seek information part of the xfer metadata, rather than an entirely
separate xfer method.

Add missing .alloc_iob entries to several xfer_interface_operations
structures.

Michael Brown 4075f7596b Unplug before sending close() message, to avoid screwing up interfaces
which respond to close with a reopen() (e.g. iSCSI).

Michael Brown b34d4d0449 Separate the "is data ready" function of xfer_seek() into an
xfer_window() function, which can return a scalar rather than a
boolean.

Michael Brown d6909f65f0 Actually, it's probably safer *not* to leave child processes hanging
around which still hold pointers to variables belonging to our parent...

Michael Brown dad5274522 Add "name" field to struct device to allow human-readable hardware device
names.

Add "dev" pointer in struct net_device to tie network interfaces back to a
hardware device.

Force natural alignment of data types in __table() macros.  This seems to
prevent gcc from taking the unilateral decision to occasionally increase
their alignment (which screws up the table packing).

Michael Brown 88e38fa148 We don't actually have a stdio.h header file. Our printf() functions are
defined in vsprintf.h.  (This may change, since vsprintf.h is a
non-standard name, but for now it's the one to use.)

There should be no need to include vsprintf.h just for DBG() statements,
since include/compiler.h forces it in for a debug build anyway.
