6b4100e1b1 Since the dynamic generation is shared between chains (for some reason) using its unified zone set, rather than keeping a special zone set per chain, which would’ve used up more zones. 
Using arena->topGen->mortality for the dynamic generation’s mortality, rather than a global variable.

bcfad58d3c Merge custom cet mainline into the master sources. this includes fixes for job003519 (clock values in text telemetry logs on windows have top 32 bits zero), job003536 (cet office can't replicate 100k snowmen in reasonable time), job003651 (stack overflows are not reliably handled).

09d0dfc481 Document the intention behind mps_ld_isstale rather than the implementation: it captures the intention of testing whether a particular dependency is stale (even though the implementation in fact tests whether any dependency is stale). add new function mps_ls_isstale_any for expressing the intention of testing whether any dependencey is stale. the two functions have the same implementation at present, but the separation gives us the freedom to return a more precise result from mps_ld_isstale in future.

ac1e57c0ac Merging branch/2013-05-17/emergency with major rework of mvt, mvff, and cbs. 
Some parts of this are still ragged, and would not normally pass review, but this is a massive improvement to the existing code.

Deprecate the format variant structures (mps_fmt_A_s, mps_fmt_B_s, mps_fmt_auto_header_s, mps_fmt_fixed_s) and the old interface (mps_fmt_create_A, mps_fmt_create_B, mps_fmt_create_auto_header, mps_fmt_create_fixed).

dd039bfbdc Fixing bugs introduced by type puns passed through scanning methods, discovered by offsetting mps_ss_s from the beginning of scanstatestruct. 
Adding a pseudo-target "find-puns" which, on FreeBSD mostly, prints useful warnings about strict aliasing rule violations.

f748ad2b28 Eliminating type puns on scan states, location dependencies, and allocation points through the mps interface.
