Always strip the modules; they are too big unstripped.  Specifically,
we generate unstripped *.elf files, and then convert them to
stripped *.c32 files.

The following conflict is a result of the fact comapi_chainboot was
only stubbed out on the 'elflink' branch but was properly marked as
obsolete in 'master'.

This patch, cleans up the DMI table structure using Lua's nested table structure and adds all missing DMI sub-tables. If a DMI sub-table is not supported by the hardware (not filled), then the corresponding sub-table will not be generated. This helps to make the table structure cleaner and reflects the actual DMI information.

In Lua.c32, the extension will be used as the following:
  1. syslinux.config_file() will return the config file string.
  2. syslinux.ipappend_strs() will return a table of IPAPPEND strings with numerical indices.
  3. syslinux.reboot() will perform cold reboot, while syslinux.reboot(1) will perform warm reboot.

This patch enables io.read() in Lua.c32 with some restrictions:
  1. the io.read("*line") is fully supported.
  2. the io.read("*number") is not supported due to the missing buffering in underlying file I/Os. However, the user can read a line using io.read() and convert the string to numbers using the built in pattern matching and number conversion features.
  3. io.read(bytes) is supported. However, io.read(0) will not be a valid test for EOF due to the missing I/O buffering. io.read() will return nil if EOF is encountered. This offers an alternative way to handle EOF.

The reason for this merge is that we need the fix to core/fs/cache.c
without which we can potentially dereference an invalid pointer.

The below conflict is a result of the new setup_data blob code being

The COM32 cs_bounce buffer is not usable with ELF modules, as we're
trying to move to an environment where memory is dynamically
allocated. All users of __com32.cs_bounce have been converted to using
lmalloc() to allocate low memory.

 getoptions() returns a table of the DHCP Options field of the BOOTP
 message returned by the DHCP server for use in a Lua pxeboot script.
 Many of the options are reurned formatted in as strings in a
 standard,
 recognizable format, such as IP addresses.

 1, 2, and 4 byte numerical options are returned as integers.

 Other Options with non-standard formats are returned as strings of
 the
 raw binary number that was returned by the DHCP server and must be
 decoded in a Lua script

 The Options table returns the Option code as the key except where
 there
 are multiple values returned. In those cases, an extra key increment
 number
 is added to allow individual access to each Option value.

      21.2                    Policy Filter [element 2]

 Options that can have a list of values, but contain only one (like
 Option 6)
 will not return with .sub key values.

 Usage:
            t = dhcp.gettable()

            for k,v in pairs(t) do
              print(k.." : "..v)
            end
