Remove limited use HAVE_ZLIB wrapper API into separate header as
utils.h is used in many places and most source files don't need
to drag in the header file from this external dependency.
Copyright date(s) taken from original source file / git blame.
When global <sys/mman.h> was removed from tile.h it also removed
<unistd.h> nearby. This exposes the lack of <unistd.h> being
included where needed using APIs like close()/read()/unlink()/isatty()
the WASM build seems to show this as the header file set is structured
differently.
When constifying there is this inconsistent quirk in this API returning
'filename' or a malloced storage. When special handling needs to be
made by the caller to detect this to decide if it needs a free.
This appears to done to save a strdup().
Make it always return a malloc block so the API contract is
strightforward to the caller. A non-NULL return requires
free() by the caller.

GCC14 -Wall cleanup series [-Wparentheses]
Previously, a file path beginning with "/", "./", or "../" would be
searched for verbatim and no searching would be done over paths.
This behavior now occurs for a leading "/" only. File paths with
"./" or "../" will search for the file with the path verbatim, then
proceed to search for the file with each search path prepended to
the filename as usual. This solves a problem for reusable, non- PDK
IP blocks, where the IP block may have an abstract view pointing to
a GDS file which is specified as being located at "../gds/<file>".
This file would not be found if the IP block was included into
another project. Now it can be done if the path to the IP is given
by "addpath".
supported). Fixed the long-standing issue in which DRC does not
get stopped by the "drc off" command (the behavior for interrupting
the DRC was dependent on the DRC being turned on, and the "drc off"
command was turning it off before breaking, causing the interrupt
to be ignored).
Compression levels of the output can be controlled with the "gds
compress [<value>]" command, where <value> 0 (default) is uncompressed
output, 6 is "normal" gzip compression, and 9 is maximum compression.
whenever a process writes a cell to disk, it immediately releases the
file lock it had on that cell, which is clearly not the intent of file
locking. Fixed this issue. On a related topic, revised the "cellname
writeable" command so that it can make a cell editable even if the cell
has an advisory lock and cannot be made writeable. Perhaps there should
be a clearer distinction here between "writeable" and "editable". Also:
Reconsidered the previous commit, which removed the "--disable-locking"
from the configuration options. Because some operating systems may not
implement fnctl()-based file locking (Cygwin, for one, apparently doesn't),
it is still useful to be able to completely remove the function, in case
the operating system will fail to recognize the fnctl() values in the
code. Now, file locking behavior can be permanently removed through the
configuration option, or temporarily disabled from the command line.
