* util/biosdisk.c: [__CYGWIN__] Add includes.
(grub_util_biosdisk_open): Use Linux code also for Cygwin.
(get_os_disk): Move variable declarations to OS specific
parts to avoid warning.
[__GNU__] (get_os_disk): Fix /dev/sdXsN case.
[__CYGWIN__] (get_os_disk): Add Cygwin /dev/sdXN device names.
(grub_util_biosdisk_get_grub_dev): Use Linux code also for
Cygwin.
* util/getroot.c: [__CYGWIN__] Add includes.
(strip_extra_slashes): Fix "/" case.
[__CYGWIN__] (get_win32_path): New function.
[__CYGWIN__] (grub_get_prefix): Add conversion to win32 path.
[__CYGWIN__] (find_root_device): Disable.
[__CYGWIN__] (get_bootsec_serial): New function.
[__CYGWIN__] (find_cygwin_root_device): Likewise.
[__linux__] (grub_guess_root_device): Add early returns to simplify
structure.
[__CYGWIN__] (grub_guess_root_device): Call find_cygwin_root_device.
[__linux__] (grub_util_get_dev_abstraction): Enable LVM and RAID
check for Linux only.
* fs/udf.c (grub_udf_mount): Fix warning about a shadowing a
variable.
* include/grub/i386/loader.h: Change declaration of
grub_linux_boot() to match what grub_loader_set() expects.
* util/getroot.c (grub_guess_root_device): Return const char* to
fix a warning.
* util/grub-probe.c (probe): Fix a warning about uninitialized
abstraction_name variable.
* util/i386/get_disk_name.c (grub_util_get_disk_name): Mark
second argument as unused to fix a warning.
* include/grub/util/getroot.h (grub_util_check_block_device): Export new
function.
* util/getroot.c (grub_util_check_block_device): New function that
returns the given argument if it is a block device and returns NULL else.
* util/grub-probe.c (argument_is_device): New variable.
(probe): Promote device_name from a variable to an argument. Receive
device_name from grub_util_check_block_device() if path is NULL and from
grub_guess_root_device() else. Do not free() device_name anymore.
(options): Introduce new parameter '-d, --device'.
(main): Add description of the new parameter to the help screen.
Rename path variable to argument. Set argument_is_device if the '-d'
option is given. Pass argument to probe() depending on
argument_is_device.
* util/getroot.c (grub_guess_root_device): Inspect /dev/evms before
/dev (like it is done for /dev/mapper). This doesn't provide support
for EVMS, but at least it is now easy to identify the problem when it
arises.
* include/grub/util/getroot.h (grub_dev_abstraction_types): New enum.
(grub_util_get_dev_abstraction): New function prototype.
* util/getroot.c: Include `<grub/util/getroot.h>'
(grub_util_get_grub_dev): Move detection of abstraction type to ...
(grub_util_get_dev_abstraction): ... here (new function).
* util/grub-probe.c: Convert PRINT_* to an enum. Add
`PRINT_ABSTRACTION'.
(probe): Probe for abstraction type when requested.
(main): Understand `--target=abstraction'.
* util/i386/efi/grub-install.in: Add abstraction module to core
image when it is found to be necessary.
* util/i386/pc/grub-install.in: Likewise.
* util/powerpc/ieee1275/grub-install.in: Likewise.
* util/update-grub_lib.in (font_path): Return system path without
converting to GRUB path.
* util/update-grub.in: Convert system path returned by font_path()
to a GRUB path. Use `grub-probe -t abstraction' to determine what
abstraction module is needed for loading fonts (if any). Export
that as `GRUB_PRELOAD_MODULES'.
* util/grub.d/00_header.in: Process `GRUB_PRELOAD_MODULES' (print
insmod commands).
* util/getroot.c (grub_guess_root_device): Remove RAID and LVM
code, first search for device in /dev/mapper, then in /dev.
(grub_util_get_grub_dev): New function.
* include/grub/util/getroot.h (grub_util_get_grub_dev): Add
prototype.
* util/grub-probe.c (probe): Remove check for RAID, call
grub_util_get_grub_dev() instead of
grub_util_biosdisk_get_grub_dev().
* util/grub-emu.c (main): Call grub_util_get_grub_dev() instead of
grub_util_biosdisk_get_grub_dev().
* util/i386/pc/grub-setup.c (main): Likewise.
* include/grub/i386/pc/util/biosdisk.h: Moved to ...
* include/grub/util/biosdisk.h: ... here.
* util/i386/pc/biosdisk.c: Moved to ...
* util/biosdisk.c: ... here.
* util/i386/pc/getroot.c: Moved to ...
* util/getroot.c: ... here.
* util/i386/pc/grub-mkdevicemap.c: Moved to ...
* util/grub-mkdevicemap.c: ... here.
