With the upcoming dynamical configuration prefix, we can no longer assume that
the prefix will start by a 'C'. As such, we can no longer hardcode this value in
the `case ...:', so replace the `switch() { ... }' statement by a more flexible
'if () { ... }' statement.

Remove the old hotkeys feature, and replace it by an interactive string
search.
From nconfig help:

Searching: pressing '/' triggers interactive search mode.
           nconfig performs a case insensitive search for the string
           in the menu prompts (no regex support).
           Pressing the up/down keys highlights the previous/next
           matching item. Backspace removes one character from the
           match string. Pressing either '/' again or ESC exits
           search mode. All other keys behave normally.

savedefconfig failed to save the correct minimal config

Consider following minimal configuration:
$cat Kconfig
choice

config A
	bool "a"

config B

$cat .config | grep -v ^#
CONFIG_A=y

$conf --savedefconfig=defconfig Kconfig

would before this fix result in an empty file, because
kconfig would assume that CONFIG_A=y is a default value.
But because the choice is optional the default is that
both A and B are =n.

If a minimal config did not specify the value
of all choice values, the resulting configuration
could have wrong values.

Consider following example:
config M
        def_bool y
        option modules
choice
        prompt "choice list"
config A
        tristate "a"
config B
	tristate "b"
endchoice

With a defconfig like this:
CONFIG_M=y
CONFIG_A=y

The resulting configuration would have

    CONFIG_A=m

which was unexpected.

The problem was not not all choice values were set and thus
kconfig calculated a wrong value.

The fix is to set all choice values when we
read a defconfig files.

conf_set_all_new_symbols() is refactored such that
random choice values are now handled by a dedicated function.
And new choice values are set by set_all_choice_values().

This was not the minimal fix, but the fix that resulted
in the most readable code.

savedefconfig will save a minimal config to a file
named "defconfig".

The config symbols are saved in the same order as
they appear in the menu structure so it should
be possible to map them to the relevant menus
if desired.

The implementation was tested against several minimal
configs for arm which was created using brute-force.

There was one regression related to default numbers
which had their valid range further limited by another symbol.

Sample:

config FOO
	int "foo"
	default 4

config BAR
	int "bar"
	range 0 FOO

If FOO is set to 3 then BAR cannot take a value higher than 3.
But the current implementation will set BAR equal to 4.

This is seldomly used and the final configuration is OK,
and the fix was non-trivial.
So it was documented in the code and left as is.

Consider following kconfig file:

	depends on TEST2

config TEST2
	bool "test 2"
	depends on TEST1

Previously kconfig would report:

foo:6:error: found recursive dependency: TEST2 -> TEST1 -> TEST2

With the following patch kconfig reports:
foo:5:error: recursive dependency detected!
foo:5:  symbol TEST2 depends on TEST1
foo:1:  symbol TEST1 depends on TEST2

Note that we now report where the offending symbols are defined.
This can be a great help for complex situations involving

Rename to a name that better match the other kconfig targets.

Do not exit with an error code if there is new options.

These are feature changes compared to the original

So drop the single letter options in favour of long options.

The long options are named equal to what we know from

resulting in much more readable code.

Support for short options is dropped - no one is supposed

Debian's ia64 autobuilders have been seeing kernel freeze or reboot
when running the gdb testsuite (Debian bug 588574): dannf bisected to
2.6.32 62eede62 "mm: ZERO_PAGE without
PTE_SPECIAL"; and reproduced it with gdb's gcore on a simple target.

I'd missed updating the gate_vma handling in __get_user_pages(): that
happens to use vm_normal_page() (nowadays failing on the zero page),
yet reported success even when it failed to get a page - boom when
access_process_vm() tried to copy that to its intermediate buffer.

Fix this, resisting cleanups: in particular, leave it for now reporting
success when not asked to get any pages - very probably safe to change,
but let's not risk it without testing exposure.

Why did ia64 crash with 16kB pages, but succeed with 64kB pages?
Because setup_gate() pads each 64kB of its gate area with zero pages.
