e570fc4070 Refine the effect of .OODATE on command comparison. 
Rather than apply it to the whole script, just the current command line
is affected.   This allows a trick like ${.OODATE:M.NOMETA_CMP}
to cause command comparison to be supressed for one command only.

c5e748dd3a fix broken logic: 
- poll can return EINTR, it is not restartable like read/write
- check poll return
- it does not make sense to check readyfd() is nready < 0
- check read return
- always call Job_CatchChildren, it is harmless
- short circuit scanning of the poll array if we got all the ready descriptors

aede2a76f4 Add a knob to control whether -V fully expands a plain variable by default. 
The default retains the traditional NetBSD behavior, but the knob
can be set so that FreeBSD can retain their expected behavior.
This is a compromise to be sure.

Add a debug flag -dV to override the above, so that regardless of
the knob setting, the raw value of a variable can be easily seen.

26aa697a51 Var* are generally very liberal with memory, with the expectation 
that none of it persists for long.
This isn't always true - for example a long running .for loop.

Buf_DestroyCompact() is used by Var_Subst(), rather than Buf_Destroy().
If it looks like we can save BUF_COMPACT_LIMIT (128) or more bytes,
call realloc.  This can reduce memory consumption by about 20%
Setting BUF_COMPACT_LIMIT to 0 dissables this.

09fee58e88 In meta mode, we create .meta files for most targets. 
These capture all the interesting data - useful for debugging.
In such cases there is no need to replicate commands in the build log.
Rather than run the entire build .SILENT, allow meta mode to set that flag
per target iff a .meta file is created.
Normal behavior is retained for targets where no .meta file is created,
ensuring that no build data is lost.

c5191c6734 If a makefile if a multiple of the page size and doesn't end with a 
newline, then it all goes horribly wrong when make tries to terminate
the last input line.
This was all ok before the mmap changes (rev 1.169) because the last
32 bytes of the input buffer were never read into.
The non-mmap case has a similar problem.
Bug found because my .depend files don't have a newline at the end of
the .OPTIO|NAL line (don't know if that is a local change).
