[dpdk-stable] [PATCH 1/3] doc: robustify PDF build

[Thomas Monjalon]

In some environment like the current dpdk.org server,
there can be some errors due to symbols in titles,
as it was the case before this commit in DPDK 18.05:
551d148944dc ("doc: remove flow API migration section")

	! LaTeX Error: Bad math environment delimiter.

It can be avoided thanks to the Latex command \robustify.

[dpdk-stable] [PATCH 2/3] doc: fix PDF with greek letter

[Thomas Monjalon]

For an unknown reason, the sign "μ" is not accepted by some environments,
probably due to the version of some Latex packages or dependencies.

	! Package inputenc Error: Unicode character μ (U+03BC)
	(inputenc)                not set up for use with LaTeX.

It is fixed by installing texlive-langgreek.
