patch 8.1.1726: the eval.txt help file is too bigv8.1.1726

Problem:    The eval.txt help file is too big.
Solution:   Split off testing support to testing.txt.  Move function details
            to where the functionality is explained.

+prop_add({lnum}, {col}, {props})
+		Attach a text property at position {lnum}, {col}.  {col} is
+		counted in bytes, use one for the first column.
+		If {lnum} is invalid an error is given. *E966*
+		If {col} is invalid an error is given. *E964*
+
+		{props} is a dictionary with these fields:
+		   length	length of text in bytes, can only be used
+				for a property that does not continue in
+				another line; can be zero
+		   end_lnum	line number for the end of text
+		   end_col	column just after the text; not used when
+				"length" is present; when {col} and "end_col"
+				are equal, and "end_lnum" is omitted or equal
+				to {lnum}, this is a zero-width text property
+		   bufnr	buffer to add the property to; when omitted
+				the current buffer is used
+		   id		user defined ID for the property; when omitted
+				zero is used
+		   type		name of the text property type
+		All fields except "type" are optional.
+
+		It is an error when both "length" and "end_lnum" or "end_col"
+		are given.  Either use "length" or "end_col" for a property
+		within one line, or use "end_lnum" and "end_col" for a
+		property that spans more than one line.
+		When neither "length" nor "end_col" are given the property
+		will be zero-width.  That means it will not be highlighted but
+		will move with the text, as a kind of mark.
+		The property can end exactly at the last character of the
+		text, or just after it.  In the last case, if text is appended
+		to the line, the text property size will increase, also when
+		the property type does not have "end_incl" set.
+
+		"type" will first be looked up in the buffer the property is
+		added to. When not found, the global property types are used.
+		If not found an error is given.
+
+		See |text-properties| for information about text properties.
+
+
+prop_clear({lnum} [, {lnum-end} [, {props}]])		*prop_clear()*
+		Remove all text properties from line {lnum}.
+		When {lnum-end} is given, remove all text properties from line
+		{lnum} to {lnum-end} (inclusive).
+
+		When {props} contains a "bufnr" item use this buffer,
+		otherwise use the current buffer.
+
+		See |text-properties| for information about text properties.
+
+							*prop_find()*
+prop_find({props} [, {direction}])
+		NOT IMPLEMENTED YET
+		Search for a text property as specified with {props}:
+		   id		property with this ID
+		   type		property with this type name
+		   bufnr	buffer to search in; when present a
+				start position with "lnum" and "col"
+				must be given; when omitted the
+				current buffer is used
+		   lnum		start in this line (when omitted start
+				at the cursor)
+		   col		start at this column (when omitted
+				and "lnum" is given: use column 1,
+				otherwise start at the cursor)
+		   skipstart	do not look for a match at the start
+				position
+
+		{direction} can be "f" for forward and "b" for backward.  When
+		omitted forward search is performed.
+
+		If a match is found then a Dict is returned with the entries
+		as with prop_list(), and additionally an "lnum" entry.
+		If no match is found then an empty Dict is returned.
+
+		See |text-properties| for information about text properties.
+
+
+prop_list({lnum} [, {props}])				*prop_list()*
+		Return a List with all text properties in line {lnum}.
+
+		When {props} contains a "bufnr" item, use this buffer instead
+		of the current buffer.
+
+		The properties are ordered by starting column and priority.
+		Each property is a Dict with these entries:
+		   col		starting column
+		   length	length in bytes, one more if line break is
+				included
+		   id		property ID
+		   type		name of the property type, omitted if
+				the type was deleted
+		   start	when TRUE property starts in this line
+		   end		when TRUE property ends in this line
+
+		When "start" is zero the property started in a previous line,
+		the current one is a continuation.
+		When "end" is zero the property continues in the next line.
+		The line break after this line is included.
+
+		See |text-properties| for information about text properties.
+
+
+						*prop_remove()* *E968*
+prop_remove({props} [, {lnum} [, {lnum-end}]])
+		Remove a matching text property from line {lnum}.  When
+		{lnum-end} is given, remove matching text properties from line
+		{lnum} to {lnum-end} (inclusive).
+		When {lnum} is omitted remove matching text properties from
+		all lines.
+
+		{props} is a dictionary with these fields:
+		   id		remove text properties with this ID
+		   type		remove text properties with this type name
+		   bufnr	use this buffer instead of the current one
+		   all		when TRUE remove all matching text properties,
+				not just the first one
+		A property matches when either "id" or "type" matches.
+		If buffer "bufnr" does not exist you get an error message.
+		If buffer "bufnr" is not loaded then nothing happens.
+
+		Returns the number of properties that were removed.
+
+		See |text-properties| for information about text properties.
+
+
+prop_type_add({name}, {props})		*prop_type_add()* *E969* *E970*
+		Add a text property type {name}.  If a property type with this
+		name already exists an error is given.
+		{props} is a dictionary with these optional fields:
+		   bufnr	define the property only for this buffer; this
+				avoids name collisions and automatically
+				clears the property types when the buffer is
+				deleted.
+		   highlight	name of highlight group to use
+		   priority	when a character has multiple text
+				properties the one with the highest priority
+				will be used; negative values can be used, the
+				default priority is zero
+		   combine	when TRUE combine the highlight with any
+				syntax highlight; when omitted or FALSE syntax
+				highlight will not be used
+		   start_incl	when TRUE inserts at the start position will
+				be included in the text property
+		   end_incl	when TRUE inserts at the end position will be
+				included in the text property
+
+		See |text-properties| for information about text properties.
+
+
+prop_type_change({name}, {props})			*prop_type_change()*
+		Change properties of an existing text property type.  If a
+		property with this name does not exist an error is given.
+		The {props} argument is just like |prop_type_add()|.
+
+		See |text-properties| for information about text properties.
+
+
+prop_type_delete({name} [, {props}])			*prop_type_delete()*
+		Remove the text property type {name}.  When text properties
+		using the type {name} are still in place, they will not have
+		an effect and can no longer be removed by name.
+
+		{props} can contain a "bufnr" item.  When it is given, delete
+		a property type from this buffer instead of from the global
+		property types.
+
+		When text property type {name} is not found there is no error.
+
+		See |text-properties| for information about text properties.
+
+
+prop_type_get([{name} [, {props}])			*prop_type_get()*
+		Returns the properties of property type {name}.  This is a
+		dictionary with the same fields as was given to
+		prop_type_add().
+		When the property type {name} does not exist, an empty
+		dictionary is returned.
+
+		{props} can contain a "bufnr" item.  When it is given, use
+		this buffer instead of the global property types.
+
+		See |text-properties| for information about text properties.
+
+
+prop_type_list([{props}])				*prop_type_list()*
+		Returns a list with all property type names.
+
+		{props} can contain a "bufnr" item.  When it is given, use
+		this buffer instead of the global property types.
+
+		See |text-properties| for information about text properties.
