6e21195890 progress: avoid NULL dereference for net files 
From original patch by dann frazier <dann.frazier@canonical.com>:

  grub_net_fs_open() saves off a copy of the file structure it gets passed and
  uses it to create a bufio structure. It then overwrites the passed in file
  structure with this new bufio structure. Since file->name doesn't get set
  until we return back to grub_file_open(), it means that only the bufio
  structure gets a valid file->name. The "real" file's name is left
  uninitialized. This leads to a crash when the progress module hook is called
  on it.

grub_net_fs_open() already saved copy of file name as ->net->name, so change
progress module to use it.

Also, grub_file_open may leave file->name as NULL if grub_strdup fails. Check
for it.

eecdbebc84 Remove mips_attributes. 
mips_attributes was introduced to work around clang problems with
-msoft-float. Those problems are now fixed and moreover .gnu_attributes
itself is unportable and creates problem with clang.

Revert "mips: Fix soft-float handling."

This partially reverts commit 6a4ecd276e.

3ac342205d arm64/setjmp: Add missing license macro 
Including the setjmp module in an arm64-efi image will cause it to
immediately exit with an "incompatible license" error.

The source file includes a GPLv3+ boilerplate, so fix this by declaring a
GPLv3+ license using the GRUB_MOD_LICENSE macro.

064360e667 Remove libgcc dependency. 
libgcc for boot environment isn't always present and compatible.
libgcc is often absent if endianness or bit-size at boot is different
from running OS.
libgcc may use optimised opcodes that aren't available on boot time.
So instead of relying on libgcc shipped with the compiler, supply
the functions in GRUB directly.
Tests are present to ensure that those replacement functions behave the
way compiler expects them to.

This module is a new implementation for reading GUID Partition Tables
which is much stricter than the existing part_gpt module and exports GPT
data directly instead of the generic grub_partition structure. It will
be the basis for modules that need to read/write/update GPT data.

The current code does nothing more than read and verify the table.
