Stephan Bergmann c8eaadb5d7 Remaining loplugin:bufferadd
...that had been missing because the plugin didn't implement postRun, so it
didn't report anything when run as part of the shared plugin.  (But did report
the expected warnings when run as a standalone plugin during
CompilerTest_compilerplugins_clang.)

Most fixes are straightforward.  A noteworthy one is PreparedStatement::setBytes
in connectivity/source/drivers/postgresql/pq_preparedstatement.cxx:  The old
preallocation of a 20 character OStringBuffer might have prevented

  buf.append( reinterpret_cast<char *>(escapedString), len -1 );

from potentially throwing std::bad_alloc, which would have caused escapedString
to be leaked.  Even though that 20-character preallocation was likely just
random junk and not meant to address the potential leak, lets address it now.

Spreadsheet application code.

You can dump some information in a dbgutil build:

=== CTRL+SHIFT+F12 ===

Dumps the column width of the first 20 columns.

=== CTRL+SHIFT+F11 ===

Dumps the graphic objects and their position and size in pixel.

=== CTRL+SHIFT+F6 ===

Dumps the SfxItemSet representing the cell properties' of the
current selection as a xml file. The file will be named dump.xml

=== The Cache Format ===

ScDocument::StoreTabToCache allows storing the content (not the formatting)
of a table to a binary cache format.

The format is column orientated which allows quick serialization of the table.

Header:
    * Number of Columns: 64 bit unsigned integer

Column:
    * Column Index: 64 bit unsigned integer
    * Column Size: 64 bit unsigned integer
    * For each cell type block a new ColumnBlock

ColumnBlock:
    * Start Row: 64 bit unsigned integer
    * Block Size: 64 bit unsigned integer
    * Type: 8 bit unsigned integer
        - 0 : empty
        - 1 : numeric
            * for each cell: 64 bit IEEE 754 double precision value
        - 2 : string
            * for each cell: 32 bit signed string length followed by string length bytes of the string (UTF-8)
        - 3 : formula
            * for each cell: 32 bit signed string length followed by the formula in R1C1 notation as a string


=== Functions supporting Wildcards or Regular Expressions ===

As this comes up every now and then, and rather should be documented in an
extra list of the Help system, functions that support Wildcards or Regular
Expressions *and* depend on the setting under
Tools -> Options -> Calc -> Calculate are those that in ODF OpenFormula (ODFF)
are defined to depend on the HOST-USE-REGULAR-EXPRESSIONS or HOST-USE-WILDCARDS
properties, see
