Convert all occurrences (353 by my count) of

	MASTER_SITES= 	site1 \
			site2

style continuation lines to be simple repeated

	MASTER_SITES+= site1
	MASTER_SITES+= site2

lines. As previewed on tech-pkg. With thanks to rillig for fixing pkglint
accordingly.

Log message:
Make this work. Add a distfile jumbo patch doing the following:
   - use standard headers
   - don't use perror, don't use sprintf
   - fix time handling issues
   - compile in paths so the data can be installed (from patch-ab)
   - fix name conflict with libc
   - avoid undefined behavior
   - avoid implicit int for clang
   - declare own functions, sprinkle const and static, and fix
     signedness to get a clean build (except for one remaining issue
     where it's not clear what to do)
   - remove unused elements detected by gcc
   - fix some problems detected by gcc
   - fix a startup crash
   - modernize the makefile

Also, don't install the raw image bitmap data and the scripts to digest
it; install only the digested form, as that's all that's used at runtime.

Otherwise, existing SHA1 digests verified and found to be the same on
the machine holding the existing distfiles (morden).  All existing
SHA1 digests retained for now as an audit trail.
