a00c4d9a69 util/DwarfReader: plug file-descriptor leaks
This change fixes several file-descriptor leaks in the DwarfReader
implementation.  The patch is taken from Richard Hellwig's not yet
merged change I161f626d12ca7f2b7b9d13ba9cbc254eb55692f1.  I did not
apply any white-space cleanups to prevent conflicts when Richard's
change will be merged later.

d68ea990ca sal: catch listener removal corner case
This change makes sure an active but not-yet fired listener does not fire
anymore if it gets removed.  In this case, the listener already has an
invalid index, but still needs to be copied to the delete list.

This issue has not been observed in the wild, and is unlikely to have
caused real problems in the past.

c4d44aeb0c sal: fix watch/breakpoint perf implementation
This commit changes the entities in a ResultSet from listener indexes
(into ListenerManagers m_BufferList) to BaseListener pointers, as
ListenerManager::makeActive(BaseListener*) (called from
FastBreakpoints/Watchpoints.ah) may invalidate indexes temporarily
stored in a ResultSet.  The issue occurs when multiple breakpoints
(watchpoints) fire at the same time, and one added more recently than
the others occupies the largest index position in m_BufferList.

Although this issue is extremely rare and was only observed in a few
corner cases up to now, it may have falsified results in the past.

e83e87ecc7 DwarfReader: fixed linetable mapping
This change alters/corrects DwarfReader's way of determining the size of
linetable entries (i.e. their "range size"); the interface (e.g. to
ElfReader) stays the same. Prior to this, it was assumed that static
instructions within "the linetable" were sorted in ascending order. This
assumption turned out to be false, as every compilation unit's  header has
its own linetable and the compilation unit headers are not sorted by their
static instructions.
Furthermore this change implements normalization of file names.

7ee105016c cmake/bochs: more strict dependency handling for libfailboch_external
The configure step for libfailbochs_external could be executed parallel
to other build steps, which required the files produced by the configure
step. Therefore a race-condition occurred. By giving the configure step
an explicit target name, more correct dependencies could be modeled
within bochs.cmake.

744ae1b7d7 util: hex and octal number support for MemoryMap
The import-trace tool supports a memorymap file as argument. Currently the
import tool accepts only decimal values, but the hexadecimal system is more
common to specify a memory address or range. To avoid a manual translation
between hex and dec values the patch extends the import tool to handle both
types according to the prefix of a value.

3fd94abcd3 cmdline: parse parameters in GNU mode
This change sets the option parser to GNU mode, that is, allows
further option parameters after non-option parameters, e.g.:

dump-trace foo.tc -s

instead of

dump-trace -s foo.tc

As Fail* currently works on GNU platforms only, this behavior is the
one presumably expected from users.

6d3ab14365 DatabaseProtobufAdapter: fix translation of unsigned fields
Independent of the protocol specification all integer fields in the
result table are signed. For instance, if I store a kernel IP (e.g.
0xf1....) the value in the database is 0x7fffffff because of the wrong
type.

Therefore, the data fields of the result table should have the same
types as specified in the protocol.

d962a322ea DatabaseProtobufAdapter: fix string insertion
This change fixes the Protobuf->MySQL bridge for strings, which were
corrupted in rare cases, especially with debug builds of the
DatabaseCampaign.  String columns in result tables from any campaign
up to this point may contain corrupted data.

The core reason for the corruption was that the TypeBridge_string
bound a temporary (a nameless local variable) to the prepared
statement.  This temporary is destroyed before the subsequent call to
mysql_stmt_bind_param(), and the string within can only be referenced
successfully if it has not been overwritten yet.  The solution is to
copy the string to a bridge-internal variable.

Although it might seem that TypeBridge_enum has the same problem, the
protobuf library seems to return references to internal string
constants when retrieving the enum values.

61050b3760 db-campaign: load completed pilots in one query
Instead of issuing a query for every variant, we assemble a set of
variant ids and query `WHERE variant_id in (1,...)'. This has not only
the effect of higher optimization potential for the database, but also
the query is issued before any result can come back. This will avoid an
overfull receive queue within the job server.

database.
