Fix infinite loop when help is bound to a named key combination.
Commit a07e8215a0ef introduced a bug in km_error_key, which is called

If help is bound to a sequence containing named keys (e.g. <esc>), the
raw (untokenized) string would be pushed back into the unget buffer.
This could lead to an infinite loop of unbound key presses triggering

Start decoupling mailbox operations.
Introduce a dedicated structure for mailbox operations: struct mx_ops.
Move the open and close operations into that structure.
Assign this structure to the context in mx_open_mailbox. This is

refactored in the future.
Add a stub mbox_close_mailbox function. This function does nothing,

Add window structures to use for screen layout.
This is a series of 11 patches, centralizing Mutt screen drawing
inside windows (mutt_window_t structures).
Currently, the screen drawing and cursor positioning logic is
distributed all over the code, resulting in many files having the same
logic of where the help, status, message windows are. Additionally,
the code directly uses move and mvadd*/mvprint* functions, which means
if the layouts are changed, the row/column computation logic needs to
be changed all over the place.
The patch creates a (very simple) mutt_window_t structure and

The windows keep track of where they are on the screen, allowing the
Mutt code to simply position elements relative to the window.

Add spacing to truncated multi-column characters when using soft-fill.

"col + pad*pw -offset"
pad = (COLS - col - wid) / pw, so this becomes

"COLS - wid - offset"
The problem is that pad was calculated *before* the right side was
mutt_wstr_trunc() truncated, which may adjust wid! We want that
calculation, with correct values, so instead just use the final
reduction directly. (Note, the reduction ignores integer truncation,
but pad shouldn't be used here in any case, because it's negative:
there is no padding occuring).
Second, when the left-hand side is truncated, multi-column characters
may get chopped in the middle. Truncated characters are not included
in the wlen and col values returned. Add spaces until the number of
columns lines up (checking to make sure we don't run out of space

Fix hcversion.h generation error when using included gettext.
When configuring mutt with --enable-hcache and

BUILT_SOURCES are processed before SUBDIRS. Therefore, the

built.
The hcversion.h target runs the cpp over config.h and mutt.h,
but mutt.h includes lib.h which tries to #include <libintl.h>.
Unfortunately, libintl.h (in this configuration) is generated by the
intl subdir build and so doesn't exist yet.

incorrect: it's just the md5sum of the initial value of BASEVERSION.
This fix is somewhat of a hack but is cleaner than trying to change
automake's behavior. It inserts a '#undef ENABLE_NLS' in between the
config.h and mutt.h sent to the cpp. Since hcachever.sh is just
scanning the data structures used by mutt, this shouldn't affect the
