Avoid cleanup problems in chroots

Don't enable formats on import or disable them on unimport unless
/proc/sys/fs/binfmt_misc is already mounted.

Fixes Debian bug #847788 and Ubuntu bug #534211.

* src/update-binfmts.c (is_enabled): New function.
(load_binfmt_misc): Use is_enabled rather than equivalent code.
(act_install): Add always_update_kernel argument. Only enable/disable
if always_update_kernel or if binfmt_misc is already enabled.
(act_remove): Add always_update_kernel argument. Only disable if
always_update_kernel or if binfmt_misc is already enabled.
(act_import, act_unimport, main): Adjust calls to act_install and
act_remove.
* NEWS: Document this.

* Makefile.am (ACLOCAL_AMFLAGS): Add -I m4.

Sort formats by name in --display

The easiest way to do this was to recast kvhash as a wrapper around a
gl_list_t (specifically a red-black tree hash) rather than a Hash_table.

* bootstrap.conf (gnulib_modules): Remove hash; add rbtreehash-list.

* src/kvhash.c (kvhash_hasher): Rename to ...
(kvhash_hashcode): ... this, make static, and replace the hash
implementation with one from Gnulib.
(kvhash_compare): New function.
(kvhash_comparator): Rename to ...
(kvhash_equals): ... this, make static, and reimplement using
kvhash_compare.
(kvhash_dispose, kvhash_dispose_plain): New functions.
(kvhash_initialize, kvhash_exists, kvhash_lookup, kvhash_insert,
kvhash_delete): Use a list rather than a hash.
* src/kvhash.h (kvhash_hasher, kvhash_comparator): Remove prototypes.
(kvhash_dispose, kvhash_dispose_plain): Add prototypes.
(kvhash_initialize, kvhash_exists, kvhash_lookup, kvhash_insert,
kvhash_delete): Update prototypes.

* src/format.c (binfmt_new): Take a list rather than a hash table.
(binfmt_hash_free): Rename to ...
(kvhash_dispose_binfmt): ... this, and update to the list API.
* src/format.h (binfmt_new): Update prototype.
(binfmt_hash_free): Rename to ...
(kvhash_dispose_binfmt): ... this, and update prototype.

* src/update-binfmts.c (formats): Declare as a list rather than a hash
table.
(get_import, act_enable, act_disable, act_import, act_display, main):
Update to the list API.

* NEWS: Document this.
