f8dae46723 New type readonlyaddr for managed address that an interface promises only to read through. 
Use ReadonlyAddr for debugging pool fenceTemplate and freeTemplate, so that we can restore -Wwrite-strings option for GCC.

eb5c7f75cc Make debugging pool implementation more flexible -- there's no longer a requirement for fencesize to be a multiple of the pool alignment, nor for freesize to be a divisor of the pool alignment. this makes it easy to write simple and portable debug options structures without having to mess about with mps_pf_align.

d3d2795fce Improve control over checking: 
1. Where Type is a pointer type with a signature, replace CHECKL(TypeCheck(val)) with CHECKD(Type, val).
2. Where Type is a pointer type with no signature, replace CHECKL(TypeCheck(val)) with CHECKD_NOSIG(Type, val).
3. Where Type is a pointer type with a signature, but the structure is not visible at point of checking, replace CHECKL(TypeCheck(val)) with CHECKD_NOSIG(Type, val). Reference <design/check/#.hidden-type>
4. Make BTCheck extern and use it where possible.
5. Replace AVER(TypeCheck(val)) with AVERT(Type, val).
