sqlite3: updated to 3.22.0

Release 3.22.0:
The output of sqlite3_trace_v2() now shows each individual SQL statement run \ 
within a trigger.
Add the ability to read from WAL mode databases even if the application lacks \ 
write permission on the database and its containing directory, as long as the \ 
-shm and -wal files exist in that directory.
Added the rtreecheck() scalar SQL function to the R-Tree extension.
Added the sqlite3_vtab_nochange() and sqlite3_value_nochange() interfaces to \ 
help virtual table implementations optimize UPDATE operations.
Added the sqlite3_vtab_collation() interface.
Added support for the "^" initial token syntax in FTS5.
New extensions:
The Zipfile virtual table can read and write a ZIP Archive.
Added the fsdir(PATH) table-valued function to the fileio.c extension, for \ 
listing the files in a directory.
The sqlite_btreeinfo eponymous virtual table for introspecting and estimating \ 
the sizes of the btrees in a database.
The Append VFS is a VFS shim that allows an SQLite database to be appended to \ 
some other file. This allows (for example) a database to be appended to an \ 
executable that then opens and reads the database.
Query planner enhancements:
The optimization that uses an index to quickly compute an aggregate min() or \ 
max() is extended to work with indexes on expressions.
The decision of whether to implement a FROM-clause subquery as a co-routine or \ 
using query flattening now considers whether the result set of the outer query \ 
is "complex" (if it contains functions or expression subqueries). A \ 
complex result set biases the decision toward the use of co-routines.
The planner avoids query plans that use indexes with unknown collating functions.
The planner omits unused LEFT JOINs even if they are not the right-most joins of \ 
a query.
Other performance optimizations:
A smaller and faster implementation of text to floating-point conversion \ 
subroutine: sqlite3AtoF().
The Lemon parser generator creates a faster parser.
Use the strcspn() C-library routine to speed up the LIKE and GLOB operators.
Improvements to the command-line shell:
The ".schema" command shows the structure of virtual tables.
Added support for reading and writing SQL Archive files using the .archive command.
Added the experimental .expert command
Added the ".eqp trigger" variant of the ".eqp" command
Enhance the ".lint fkey-indexes" command so that it works with WITHOUT \ 
ROWID tables.
If the filename argument to the shell is a ZIP archive rather than an SQLite \ 
database, then the shell automatically opens that ZIP archive using the Zipfile \ 
virtual table.
Added the edit() SQL function.
Added the .excel command to simplify exporting database content to a spreadsheet.
Databases are opened using Append VFS when the --append flag is used on the \ 
command line or with the .open command.
Enhance the SQLITE_ENABLE_UPDATE_DELETE_LIMIT compile-time option so that it \ 
works for WITHOUT ROWID tables.
Provide the sqlite_offset(X) SQL function that returns the byte offset into the \ 
database file to the beginning of the record holding value X, when compiling \ 
with -DSQLITE_ENABLE_OFFSET_SQL_FUNC.
