bda6a60ad4 Windows fixes 
Always set the filesize when opening for writes. Otherwise
can't use backups from mdb_copy.

f3573a7383 Windows compat 
We mainly use Win32 functions, so cannot just use C-runtime strerror
to return error messages. We have to use Win32-specific messages.
Unfortunately, we document the API to return C-runtime error codes,
so we can't just switch to all Win32 error codes.

persist size changes from env_open() as well. This was the
original behavior.

a5e4eecb1e Revert "ITS#7789 update RESIZED errmsg text" 
This reverts commit d8e18551c3.
And partially reverts mapsize check. Only mapsize increases are relevant.

d5371347e8 ITS#7825 more 
Set read txn's dbiseqs to env's. Set child txn's dbiseqs to parent's.
Simplify DBI_CHANGED test, no need to check md_name. No-op dbi_close
of already closed handle.

that was not requested by this process.

e1a676eb18 ITS#7713 cleanups 
'#ifdef MDB_DEVEL' -> '#if MDB_DEVEL'
Fix comments, use actual PAGEBASE macro as originally intended.
Actually enable 64K pages. Set MDB_DATA_VERSION for testing only.

6ed295b256 Fixes for loose pages 
mdb_txn_commit(child): Give loose pages to parent.
Use a pointer beyond the page header instead of mp_next, so
we will not need to save/restore mp_pgno. This avoids a crash
caused by references to mp_pgno.

68e6faad5c ITS#7713 handle 65536 byte page size 
Fix mp_lower/mp_upper to exclude PAGEHDRSZ, which means our
max mp_upper is now pagesize - PAGEHDRSZ and won't overflow.
Currently must define MDB_DEVEL to use. Will be default for
LMDB 1.0/OpenLDAP 2.5

4009c9ae65 Add mdb_env_copy2() 
And mdb_env_copyfd2(). Perform compaction on the copy. Trims out
freed pages and renumbers data pages in sequential order. This is
more CPU-intensive since it copies and modifies data pages.

91d8ad1d3c Fix mdb_page_loose() vs. mdb_page_flush(). 
Do not overwrite loose pages' mp_pgno with mp_next.
mdb_page_flush() will use mp_pgno to rebuild dirty_list.

c73f087750 Trap signals

a critical issue since mdb_reader_check can take care of
them, but still cleaner.
