1st struct member was not a scalar.

Preserve DB flags (use metapage#1) when main DB is empty.
Fail if metapage root != actual root in output file.

Handle errors.  Fix cond_wait condition so mc_new
is the sole control var.  Drop specious cond_waits.
Do not look at 'mo' while copythr writes it.

Don't know if posix_memalign() pointer is defined after failure.
Some _aligned_free() doc seems to say arg NULL = user error.

Revert excess cursor fixup
xcursor fixup depends on init state

No change in behavior.

Check for PTHREAD_MUTEX_ROBUST_NP definition (this doesn't work
on Linux/glibc because they used an enum). Zero out mutex before
initing.

Don't leave them uninit'd if they now point at a valid DUP node

If we know there are no sub-DBs and no overflow pages, skip leaf scan.

make sure C_DEL gets reset in subcursor after it moves.

Only try to write 1GB at a time on Windows64;
larger writes fail with ERROR_WORKING_SET_QUOTA.

From 1ba5adb2 "MDB_VL32 preparation".

Let "illegal" branch pages thru on the FreeDB - the condition
is only temporary and will be fixed by the time rebalance finishes.

Add mdb_put text to mdb_cursor_put description for people who
fail to draw logical conclusions.
