1) Added a "*showmem" "wizard" command to get a dump of all memory
being used by tiles in the database.
2) Made a slight correction to the way magic detects exact overlap
of instances of the same cell. This probably does not make any
actual difference in practice.
3) Corrected an uninitialized variable in dbReComputeBboxFunc().
4) Changes DBSrCellPlaneArea() to use a static BPEnum variable, so
that it does not waste time allocating and freeing memory for
the same thing over and over again.
5) Corrected a memory leak in the tech file "extract" section that
loses memory every time the extraction style is changed.
6) Corrected the tile join routines to fix a bad memory leak in the
tile allocation and recovery---a fix which was mentioned in issue
#414 but which had not yet been implemented. This has now been
tested and confirmed to work.

GCC14 -Wall cleanup series [-Wparentheses]
check was too aggressive and would delete coincident instances
based on cell def and bounding box only. If the cells were at
different orientation or mirrored, they would be incorrectly
flagged as coincident. Instances read from GDS could be
deleted due to this issue.
for saving on a cell which is completely unmodified. One of these
was due to the BPlane implementation, which forces an instance to be
deleted and re-placed on a bounding box recomputation, which should
not, in that case, be considered a modification. Another always runs
DRC on a subcell upon reading rather than relying on any checkplane
entries in the file itself; and the last one marking the timestamp
as modified stemming from an attempt to correct an O(N^2) check to
O(N). All three cases have now been corrected.
related to that cell (since elements are usually temporary and so
kept in a separate list, not in the cell). Corrected a major error
in the bplane implementation that failed to remove a cell use from
the child def's parent list when deleting the use. Can cause magic
to go into an infinite loop, especially after selecting and unselecting
cells.
called the undo record generation twice when transforming (move,
copy, etc.) cell instances. This would cause the "undo" command
to regenerate the old instance position in the bplane records,
generally causing trouble down the road (did not encounter any
fatal errors, but it can't be good).
