Fix bugs #8546 and #9055, and introduce new separator inset. The algorithm used for breaking a paragraph in LaTeX export is changed for avoiding spurious blank lines causing too much vertical space. This change is tied to the introduction of a new inset (with two different specializations) helping in either outputing LaTeX paragraph breaks or separating environments in LyX. Both of the above goals were previously achieved by the ---Separator--- layout and can now be accomplished by the new inset in a more natural way. As an example, after leaving an environment by hitting the Return key for two times, a third return automatically inserts a parbreak inset, which is equivalent to the old separator layout, i.e., it also introduces a blank line in the output. If this blank line is not wanted, the parbreak separator can be changed to a plain separator by a right click of the mouse. Of course, an environment can still be separated by the following one by using the Alt+P+Return shortcut (or the corresponding menu key), but now the plain separator inset is used instead of the old separator layout, such that no blank line occurs in the LaTeX output. Old documents are converted such that the LaTeX output remains unchanged. As a result of this conversion, the old separator layout is replaced by the new parbreak inset, which may also appear in places where the old algorithm was introducing blank lines while the new one is not. Note that not all blank lines were actually affecting the LaTeX output, because a blank line is simply ignored by the TeX engine when it occurs in the so called "vertical mode" (e.g., after an alignment environment). The old ---Separator--- layout is now gone and old layout files using it are also automatically converted. Round trip conversions between old and new format should leave a document unchanged. This means that the new behavior about paragraph breaking is not "carried back" to the old format. Indeed, this would need introducing special LaTeX commands in ERT that would accumulate in roundtrip conversions, horribly cluttering the document. So, when converting a modified document to old formats, the LaTeX output may slightly differ in vertical spacing if the document is processed by an old version of LyX. In other words, forward compatibility is guaranteed, but not backwards.

The implementation is self-explaining, the only part which needs a comment is lyx2lyx: Since a 100% correct solution is not possible, it has been decided not to switch amsmath off in the forward conversion if no other ams command than \smash[t] and \smash[b] is used, but to consider it a bug that older versions do not load amsmath automatically for these commands.

Fix bugs #8546 and #9055, and introduce new separator inset. The algorithm used for breaking a paragraph in LaTeX export is changed for avoiding spurious blank lines causing too much vertical space. This change is tied to the introduction of a new inset (with two different specializations) helping in either outputing LaTeX paragraph breaks or separating environments in LyX. Both of the above goals were previously achieved by the ---Separator--- layout and can now be accomplished by the new inset in a more natural way. As an example, after leaving an environment by hitting the Return key for two times, a third return automatically inserts a parbreak inset, which is equivalent to the old separator layout, i.e., it also introduces a blank line in the output. If this blank line is not wanted, the parbreak separator can be changed to a plain separator by a right click of the mouse. Of course, an environment can still be separated by the following one by using the Alt+P+Return shortcut (or the corresponding menu key), but now the plain separator inset is used instead of the old separator layout, such that no blank line occurs in the LaTeX output. Old documents are converted such that the LaTeX output remains unchanged. As a result of this conversion, the old separator layout is replaced by the new parbreak inset, which may also appear in places where the old algorithm was introducing blank lines while the new one is not. Note that not all blank lines were actually affecting the LaTeX output, because a blank line is simply ignored by the TeX engine when it occurs in the so called "vertical mode" (e.g., after an alignment environment). The old ---Separator--- layout is now gone and old layout files using it are also automatically converted. Round trip conversions between old and new format should leave a document unchanged. This means that the new behavior about paragraph breaking is not "carried back" to the old format. Indeed, this would need introducing special LaTeX commands in ERT that would accumulate in roundtrip conversions, horribly cluttering the document. So, when converting a modified document to old formats, the LaTeX output may slightly differ in vertical spacing if the document is processed by an old version of LyX. In other words, forward compatibility is guaranteed, but not backwards.

Native support for \smash[t] and \smash[b] This is a follow-up of bug #8967. The implementation is self-explaining, the only part which needs a comment is lyx2lyx: Since a 100% correct solution is not possible, it has been decided not to switch amsmath off in the forward conversion if no other ams command than \smash[t] and \smash[b] is used, but to consider it a bug that older versions do not load amsmath automatically for these commands. In the backward direction it is easy to keep the document compilable, so just do that.
