d62c464541 speedtest1.js: only install opfs-sahpool if it's provided via --vfs flag, to avoid locking errors in concurrent speedtest1 tabs with other VFSes. Add opfs-sahpool reserveMinimumCapacity().

aa1b2a80ee During "opfs" VFS init, check for URL param opfs-disable and, if set, do not install the VFS. Added per forum suggestion to provide a way to help rule out misinteraction between the "opfs" and "opfs-sahpool" VFSes.

bee3213145 Switch opfs-sahpool to use deterministic backing-store file names. Delay VFS registration until after the pool's files are all opened. Fail vfs init if the client's OPFS API has an async FileSystemSyncAccessHandle.close() method (indicating that it's outdated).

flag, the pager is opened in journal-mode MEMORY, even if compiled with
SQLITE_OMIT_DESERIALIZE.  No changes to the logic as long as that OMIT flag
is omitted.  We need to better document the behavior of xOpen to describe this.

7520116441 Simplify a memcpy() in defragmentPage(). It now might copy more content than 
is strictly necessary, but runs faster and uses less code space.  Possible
reasons for the improved performance:
(1) the copy is now always 8-byte aligned,
(2) fewer intermediate results are required which means less register
pressure which helps the compiler to optimize the subroutine.

Enhance pagerExclusiveLock() to deal with this.
