provided for data so that it is big enough to cover the increased number of
bytes displayed during register tracing from check-in [54553bf16fabd72d].
This is the correct fix for ticket [bbd55a97e66ff50d], though the earlier one
does not hurt and is useful to retain.

the safer StrAccum interface rather than writing directly into a static string
buffer. Perhaps this will address ticket [bbd55a97e66ff50d], which we are
unable to reproduce.

In PRAGMA vdbe_trace=on output, show pScopyFrom dependencies on register
values. Add the sqlite3VdbeRegisterDump() procedure, callable from a
debugger, that shows the values of all registers. Pass the VDBE pointer
into test_trace_breakpoint() so that sqlite3VdbeRegisterDump() is callable
from the breakpoint.

SQLITE_DEBUG builds. Also add parameters "pc" and "pOp" to
test_addop_breakpoint() to make it easier to set conditionals.

by adding the new OP_ReleaseReg opcode to tell MemAboutToChange() that a
range of registers is no longer needed so that the source register can be
freely changed. This is a change to debugging and test builds only and
does not impact release builds. Fix for ticket
[c62c5e58524b204d] and [5ad2aa6921faa1ee]. The previous fix to ticket
[5ad2aa6921faa1ee] is backed out by this change since this change is a better
fix.
