Prevent assert at frame.c, l. 6311 by initializing glyph cachels. * frame.c (Fmake_frame): Ensure that reset_glyph_cachels gets called. (setup_minibuffer_frame): Improve header comment. * redisplay.c (redisplay_window): Update comment. Remove code checking for uninitialized face_cachels and glyph_cachels. Can't happen in theory, and guarded by asserts in practice. * window.c (allocate_window): Update comment on reset_*_cachels.

/* How this works:

 Fdump_emacs dumps everything up to my_edata as text space (pure).

 The files of Emacs are written so as to have no initialized
 data that can ever need to be altered except at the first startup.
 This is so that those words can be dumped as sharable text.

 It is not possible to exercise such control over library files.
 So it is necessary to refrain from making their data areas shared.
 Therefore, this file is loaded following all the files of Emacs
 but before library files.
 As a result, the symbol my_edata indicates the point
 in data space between data coming from Emacs and data
 coming from libraries.
