832ee3d4cc Optimize the degenerate case of a FROM clause table name enclosed all by 
itself inside parentheses.  Generate code as if the parentheses did not
exist, rather than the old behavior of manifesting the parenthesized table
into a transient table.  Also, tag every FROM-clause SELECT subquery that is
generated by a parenthesized FROM-clause expression using the SF_NestedFrom
flag.  The new SF_NestedFrom flag is not yet used for anything.

985cd59c48 On atomic-write capable systems, if copying the contents of an in-memory journal to disk fails, close the (on disk) journal file before returning the error to the caller. This causes the subsequent rollback operation to use the in-memory journal. Fix for [df678d738adb].

468ef9a87e Refactor collating-sequence handling as a fix for ticket [71e333e7d2e642]. 
The Expr.pColl field is removed from the Expr object.  The COLLATE operator
now becomes a separate instance of Expr in the expression tree.  The code
generator looks up the correct collating function as needed, rather than
referring to Expr.pColl.

0fbb50ee15 When available, use posix_fallocate() rather than ftruncate() to allocate 
space for mmap()ed -shm files, since posix_fallocate() gives an error if
no disk space is available whereas ftruncate() is silent and leaves the system
vulnerable to a SIGBUS upon first write to the mmap()ed region.
