Deduplicates and generalises a lot of code in assign.c:
- Replace area_AllocAbs*AnyBank() with area_AllocAbsAnyBank() function
that accepts a section type parameter
- Replace area_Alloc*AnyBank() with area_AllocAnyBank()
- Replace FindLargest*() with FindLargestSection()
- Replace Assign*Sections() with AssignBankedSections()
- Add VerifyAndSetBank(), which enables bank checks (and addition with
BANK_*) to be centralised
- Refactor the initialisation of AssignSections(), removing some magic
numbers and only setting MaxAvail[i] once
- Overhaul the duplicated cases throughout AssignSections()
Merging lai's source with this one is very irritating because
they have different indentation styles. I couldn't find what profile
vegard used for his version, so I used these flags (which should bring
the source close to KNF):
-bap
-br
-ce
-ci4
-cli0
-d0
-di0
-i8
-ip
-l79
-nbc
-ncdb
-ndj
-ei
-nfc1
-nlp
-npcs
-psl
-sc
-sob
