Change pg_bsd_indent to follow upstream rules for placement of comments
to the right of code, and remove pgindent hack that caused comments
following #endif to not obey the general rule.
Commit e3860ffa4dd0dad0dd9eea4be9cc1412373a8c89 wasn't actually using
the published version of pg_bsd_indent, but a hacked-up version that
tried to minimize the amount of movement of comments to the right of
code. The situation of interest is where such a comment has to be
moved to the right of its default placement at column 33 because there's
code there. BSD indent has always moved right in units of tab stops
in such cases --- but in the previous incarnation, indent was working
in 8-space tab stops, while now it knows we use 4-space tabs. So the
net result is that in about half the cases, such comments are placed
one tab stop left of before. This is better all around: it leaves
more room on the line for comment text, and it means that in such
cases the comment uniformly starts at the next 4-space tab stop after
the code, rather than sometimes one and sometimes two tabs after.
Also, ensure that comments following #endif are indented the same
as comments following other preprocessor commands such as #else.
That inconsistency turns out to have been self-inflicted damage
from a poorly-thought-through post-indent "fixup" in pgindent.
This patch is much less interesting than the first round of indent
changes, but also bulkier, so I thought it best to separate the effects.

The new indent version includes numerous fixes thanks to Piotr Stefaniak.
The main changes visible in this commit are:
* Nicer formatting of function-pointer declarations.
* No longer unexpectedly removes spaces in expressions using casts,
sizeof, or offsetof.
* No longer wants to add a space in "struct structname *varname", as
well as some similar cases for const- or volatile-qualified pointers.
* Declarations using PG_USED_FOR_ASSERTS_ONLY are formatted more nicely.
* Fixes bug where comments following declarations were sometimes placed
with no space separating them from the code.
* Fixes some odd decisions for comments following case labels.
* Fixes some cases where comments following code were indented to less
than the expected column 33.
On the less good side, it now tends to put more whitespace around typedef
names that are not listed in typedefs.list. This might encourage us to
put more effort into typedef name collection; it's not really a bug in
indent itself.
There are more changes coming after this round, having to do with comment
indentation and alignment of lines appearing within parentheses. I wanted
to limit the size of the diffs to something that could be reviewed without
one's eyes completely glazing over, so it seemed better to split up the
changes as much as practical.

Previously, text between backquotes in a psql metacommand's arguments
was always passed to the shell literally. That considerably hobbles
the usefulness of the feature for scripting, so we'd foreseen for a long
time that we'd someday want to allow substitution of psql variables into
the shell command. IMO the addition of \if metacommands has brought us to
that point, since \if can greatly benefit from some sort of client-side
expression evaluation capability, and psql itself is not going to grow any
such thing in time for v10. Hence, this patch. It allows :VARIABLE to be
replaced by the exact contents of the named variable, while :'VARIABLE'
is replaced by the variable's contents suitably quoted to become a single
shell-command argument. (The quoting rules for that are different from
those for SQL literals, so this is a bit of an abuse of the :'VARIABLE'
notation, but I doubt anyone will be confused.)
As with other situations in psql, no substitution occurs if the word
following a colon is not a known variable name. That limits the risk of
compatibility problems for existing psql scripts; but the risk isn't zero,
so this needs to be called out in the v10 release notes.

Brain fade in commit a00c58314: I was thinking that a string starting with
"-" could be taken as a switch depending on command line syntax. That's
true, but having appendShellString() quote it will not help, so we may as
well not do so. Per complaint from Peter Eisentraut.

The original coding here was not nearly careful enough about quoting
special characters, and it didn't get corner cases right for constructing
the pg_ctl path either. Use join_path_components() and appendShellString()
to do it honestly, so that the string will more likely work if blindly
copied-and-pasted.
While at it, teach appendShellString() not to quote strings that clearly
don't need it, so that the output from initdb doesn't become uglier than
it was before in typical cases where quoting is not needed.

This is somewhat cosmetic, since as long as you know what you are looking
at, "10.0" is a serviceable substitute for "10". But there is a potential
for confusion between version numbers with minor numbers and those without
--- we don't want people asking "why is psql saying 10.0 when my server is
10.2". Therefore, back-patch as far as practical, which turns out to be
9.3. I could have redone the patch to use fprintf(stderr) in place of
psql_error(), but it seems more work than is warranted for branches that
will be EOL or nearly so by the time v10 comes out.
Although only psql seems to contain any code that needs this, I chose
to put the support function into fe_utils, since it seems likely we'll
need it in other client programs in future. (In 9.3-9.5, use dumputils.c,
the predecessor of fe_utils/string_utils.c.)
In HEAD, also fix the backend code that whines about loadable-library
version mismatch. I don't see much need to back-patch that.

Due to simplistic quoting and confusion of database names with conninfo
strings, roles with the CREATEDB or CREATEROLE option could escalate to
superuser privileges when a superuser next ran certain maintenance
commands. The new coding rule for PQconnectdbParams() calls, documented
at conninfo_array_parse(), is to pass expand_dbname=true and wrap
literal database names in a trivial connection string. Escape
zero-length values in appendConnStrVal(). Back-patch to 9.1 (all
supported versions).

Rename these newly-extern functions with terms more typical of their new
neighbors. No functional changes; a subsequent commit will use them in
more places. Back-patch to 9.1 (all supported versions). Back branches
lack src/fe_utils, so instead rename the functions in place; the
subsequent commit will copy them into the other programs using them.

Reference to getThreadLocalPQExpBuffer here seems inappropriate, since
we aren't necessarily using that instantiation of getLocalPQExpBuffer.

Move fmtReloptionsArray() from pg_dump.c to string_utils.c so that it
is available to other frontend code. In particular psql's \ev and \sv
commands need it to handle view reloptions. Also rename the function
to appendReloptionsArray(), which is a more accurate description of
what it does.

Per discussion, we want to create a static library and put the stuff into
it that until now has been shared across src/bin/ directories by ad-hoc
methods like symlinking a source file. This commit creates the library and
populates it with a couple of files that contain the widely-useful portions
of pg_dump's dumputils.c file. dumputils.c survives, because it has some
stuff that didn't seem appropriate for fe_utils, but it's significantly
smaller and is no longer referenced from any other directory.
Follow-on patches will move more stuff into fe_utils.
The Mkvcbuild.pm hacking here is just a best guess; we'll see how the
buildfarm likes it.
