* Add 'name' property to Identifier
* Rename to unescapedText
* Rename 'id.text' to 'id.escapedText'
* Rename 'id.unescapedText' to 'id.text'
* Make escapeIdentifier and unescapeIdentifier do nothing

* Don't call tryGetModuleNameFromDeclaration on a synthesized importNode
* Apply suggested changes
Now Typescript supports the creation of anonymous types using successive
`@param` lines in JSDoc:
```js
/**
* @param {object} o - has a string and a number
* @param {string} o.s - the string
* @param {number} o.n - the number
*/
function f(o) { return o.s.length + o.n; }
```
This is equivalent to the Typescript syntax `{ s: string, n: number }`,
but it allows per-property documentation, even for types that only need
to be used in one place. (`@typedef` can be used for reusable types.)
If the type of the initial `@param` is `{object[]}`, then the resulting
type is an array of the specified anonymous type:
```js
/**
* @param {Object[]} os - has a string and a number
* @param {string} os[].s - the string
* @param {number} os[].n - the number
*/
function f(os) { return os[0].s; }
```
Finally, nested anonymous types can be created by nesting the pattern:
```js
/**
* @param {Object[]} os - has a string and a number
* @param {string} os[].s - the string
* @param {object} os[].nested - it's nested because of the object type
* @param {number} os[].nested.length - it's a number
*/
function f(os) { return os[0].nested.length; }
```
Implementation notes:
1. I refactored JSDocParameterTag and JSDocPropertyTag to
JSDocPropertyLikeTag and modified its parsing to be more succinct. These
changes make the overall change easier to read but are not strictly
required.
2. parseJSDocEntityName accepts postfix[] as in `os[].nested.length`,
but it doesn't check that usages are correct. Such checking would be
easy to add but tedious and low-value.
3. `@typedef` doesn't support nested `@property` tags, but does support
`object[]` types. This is mostly a practical decision, backed up by the
fact that usejsdoc.org doesn't document nested types for `@typedef`.
We just merged a change which makes the `.types` member of a union or intersection type a readonly array. Our lint rule's type annotation needs to reflect that.
